Yeah i suffer from social anxiety and generalised anxiety disorder. They both suck. Luckily for me I don't often get panic attacks- but I still feel super anxious in social situations- so much that it's sometimes hard to leave my room, especially alone. I'll keep my head down when walking- especially down a busy road where cars are coming the opposite way- I get paranoid they are looking at me as they go past. I have a lot of issues with self esteem and feel ugly which is why I get so paranoid I think. Then there's eye contact which I struggle with. I can often have a whole conversation without once making eye contact because I find it easier. I've lost a lot of 'friends' by being socially awkward, because I find it hard to maintain conversation and I'm often left out of social events because of it.
Generalised anxiety also means these social situations put thoughts in my head that I can't get rid of, even when I'm alone and back at home in my 'comfort zone'. I think about the situation, and anything embarrassing I might of done. I sit there wondering if people actually like me, or were pretending. I overthink each situation I have been in, or am going to be in, and sometimes talk myself out of happiness. For example if I have had a good night, and have enjoyed myself with people- i'll somehow convince myself of something that will make me think I am not liked, or that people think of me in a certain way, and I ruin it for myself. I'm on medication but it's not the best and it doesn't make much of a difference.
I know it sucks having anxiety, but you're not alone. So many people suffer with it, and they come in different ways. Advice would be to talk to somebody if you haven't already- such as a doctor or a school/uni/college counselor/mental health expert. It is so so hard keeping everything inside because you feel like bursting. I know a few people wth depression and anxiety but they aren't the type of people I can talk to. They are so open about it and it's almost as if they enjoy speaking about it, but I just can't do that. So yeah, if you can seek help, do it. I went to my doctor and got some meds, which are effective with some people, so maybe try that and see what happens. In the mean time, I'm here if you need to talk, and keep your chin up and keep going. You're not alone x
