Anxiety at school

I mean it's not great at the time but your school days they ain't something that will last forever, in fact it goes very quickly really in the grand scheme of life and 99% of the people you socialise while your there you'll never see them again.

All I'm getting at here is the social rules change drastically once you leave school and I knew plenty of people who weren't very popular kids at school but their confidence grew once they'd left school and they could be more selective in who they spent their time with and what they did with their lives.

I know that does help the right here and now but stay strong and concentrate on getting the grades you might need and trust me things will honestly things get better once you leave you'll never have to go back to dealing with 30-40 random giggling school kids packed in a classroom ever again and your confidence will grow.

i had this exact problem, in class i would just get anxious out of nowhere but listen, now i see that the kids that werent nice to me had a lot off problems like me too and that was their way of venting so it wasnt my fault, when i had to present sth i saw that in some time i wasnt even gonna remember that moment and no one else either, and i thought why does it even matter? literally everything except death has a solution, and with time i stopped giving a damn and my confidence just went out naturally

Have you talked to a doctor about this? Anxiety have actual biological and physical symptoms that you can get treatment for. Therapy can help ward stuff off for many people but some people need extra help to control the symptoms.

Don't do it...Tell them no.
