sixth form social struggles

I feel quite sad and out of place in sixth form right now. It used to be a lot better, especially in the first half-term when everyone was getting to know each other and life was quite chill (no academic pressure.) I feel like some girls and boys gravitated towards me and genuinely enjoyed my presence at that point in time. In one party a while ago around when school started, I was quite drunk (like most people there) and over spoke a bit and acted a bit goofy, but is that even a big deal? Lots of girls and boys do crazy stuff like back-stab, talk bad, date and have messy breakups and make out + throw up etc. I didn't even do anything bad or rude since then, but I have a deep gut feeling that I am disliked and 'weird' in the social aspect. In the beginning of school, people invited me to 4/5 parties (which is a LOT!) For the first half term, I went out most weekends. In the second half term, I still had friends but it fizzled out a bit and I feel like people grouped up and left me in an awkward groupless position. Since January, I have been actively trying to hang out with people and diversify my social connections, but it feels like they allow me to sit/hang out with them, but I am not 'one of them.' When I talk to them, they respond nicely and let me sit there, but will not really approach me first much. Also, a girl I was close to in the first term doesn't talk to me that much anymore, but I think we are civil (she is friendly enough when we interact occasionally, and obviously groups shift.) To be fair, I need to ask more girls and boys to hang out with me, as in the past people would do so to me, but I never really asked people first. Of course, friends can not just be given out like amazon packages. How can I get invited to parties again? What if I gently ask someone if I can come, as I have invited them to parties in the past when they weren't invited. I am really scared and have a gut feeling that I am slightly socially rejected/marginalised, but I am an overthinker and I give people's opinions too much importance due to my own low self esteem. In fact, it is possible that people like me but my own mental blocks and anxiety prevents me from solidifying good friendships. Do I need to ask people to hang out, or maybe I should do something to increase my visibility in the social aspect (advice please e.g. post on insta/tiktok to seem 'cool' and 'confident.') I really would like some good advice, as it is March already and school ends in 4ish months, and I haven't fully taken hold of the experience which my parents pay A LOT for. I think I heard a dude say I have a lack in certain social areas, and a girl said something vaguely similar. (but the girl is a freak herself so idc about her opinion.) What does this mean about me, and how can I improve it? In conversations, I frequently ask questions, seem involved and have made people laugh before. I am just a bit insecure of myself, but I DO TALK to others, and include myself and try to seem secure (how would they really know?) I feel like I have been spiralling since the party, in which I didn't even do anything cruel or bad. Some people in school settings are 'strange NPCs', and I am scared that is me for some reason. I want people to enjoy my presence, like my company and truly think I am normal and a cool and chill girl. Please give me some good advice on this, for a sixth form teen Y12 girl going to a private school in the UK. Please tell me how to know what people really think of me, how to improve my social impression and standing, let me know if I am actually hated and weird, or self-isolating due to a fear of it, and how to increase my visibility and get invited to more social events. I need actual clear actionable feedback e.g. ask the girl in your German class to go out with you for dinner or gently ask someone who is hosting about it and say it sounds fun etc. Please tell me if I am really that messed up or not. Many girls have actually had beef with others, resulting in solid conflicts. I haven't, so surely I can't be that hated. Also, a girl I thought smirked when I sat down next to her came up to me yesterday at a school event, hugged me and complimented me. I used to think she disliked me, but maybe she didn't as why would she be sweet to me if she thought I wasn't cool. Also, in terms of being a nice social person, how do I improve this e.g. make eye contact, modulate voice or things to say to people in social settings without seeming off-putting and odd. Just to add, I have NEVER asked anyone to hang out with me first, or show real interest in pursuing a friendship other than eating with them at lunch and liking and commenting on their posts, or saying nice things around them at school. Also, is it weird or possible to compliment people too much?

Thank you for your feedback. On Monday, I will ask some people to hang out with me. Actually, thanks for your feedback on the too many compliments thing. Actually, someone picked up on it and said it's a bit weird but I am still nice, but just as a passing comment ages ago. I have not really interacted with them for a while, will they be chill with me now since I stopped doing that, and I have not been talking to them for 3ish/4 months now? I think I may approach them and make small talk if that is a good way to make a better impression and start clean without overdoing the niceness. Also, please tell me truly if I have a personality issue, or if people dislike me due to the party thing ages ago? I do actually want to go to parties (alongside nice fun social interactions like bowling and the movies etc.), is there a reason why I am not invited right now? Perhaps my social visibility and choice/amount of friends. Sorry for the overflow of questions, I am just keen for some answers.

okay, but based on what you described and the fact that I can not see the counsellor due to personal reasons, do you think there is really the issues I detailed above, or is it more of a mental freak-out on my behalf? Please let me know what you think based on my original post, and my questions above. Thanks so much!

I didn't make many friends in the sixth form, and I didn't stay friends with any of them when it ended. If you feel like you're doing badly socially at this point, you need to not make the mistakes I made and nip this in the bud whilst you still can.

what do you mean by that? How do I improve and not be in that situation

You've already come up with ways to hopefully get closer to the other people in your sixth form. Ultimately some people don't get along with people as well as others do (I am certainly in that group) but there will be a point where other people might begin to think you're not worth their time anymore.
All I can suggest is to try to come across as normal and friendly, and try to get to know the people you have things in common with more.

sure, can u give me examples of ways to seem more normal and friendly without being lowkey creepy and too nice. Also, what do u mean by ") but there will be a point where other people might begin tothink you're not worth their time anymore.' Is this in a sense of time-period, or after doing something specific?

okay... can someone give me more advice please??

I feel like everyone smirks and hates when I seem to be around, moving away from me and giggling and when I try to join a conversation they run away. Should I confront them or leave it? I haven't done anything to anyone, but I feel deeply that they all mock me. For example, many do not accept me onto their private accounts, making me feel like a social reject. Am I actually weird and messed up? What makes 16 year old girls dislikable?

probably the first option for socials. for a friend who has been awkward to me since the beginning of January after the Christmas holidays, who I was besties with before, should I ask her what happened or not? How do I become genuinely charismatic and someone that people want to talk to. It feels like I have bad breath or a lisp, when people first meet me they love me for a few months/ few conversations, then they realise that I am somehow fundamentally flawed and leave me completely. What do I do?

I feel like people talk about me behind my back or something, because when I talk a couple girls/boys often smirk and when I join conversations they walk away. Maybe she said something to them, even tho I did nothing. Or I could be overthinking. Some people are different and weird at their core, there is just something "wrong' and "different" about them. Could this be me? How do I know If it is....
