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?

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?

Things are so much better!! Feeling well settled, integrated and rather happy. Made friends, in solid groups and somewhat thriving. Thank you all. Although, I could go out more with friends, which is my only complaint. I have a question about a guy, who I want to know something about.
