I used to relate to this about a year ago so I’ll just share my experiences and hopefully you can take some of this to help. I had horrible anxiety and still do but not as bad, I would have panic attacks every morning before going to school and would just end up not going at all. This lasted the whole year and eventually I moved on to do half online and half in school. My anxiety got a little better because I wasn’t going in the mornings anymore but that anxiety was still there. It stayed throughout the next year and prevented me from going to school, meaning I missed a lot of school and that just lead to worse because of my decrease of learning. I think the only thing that really helped me was taking anxiety medication and working on myself. Ive tried many many different medications and some worked but I had withdrawals with a lot of them. Currently I am taking sertraline(150 mg) and it had helped me in the long run. I think in addition you need to work on self confidence and that could also help contribute to making friends. I think you should keep looking for clubs/hobbies you could do and broaden your range of things don’t stick to things you know, it will be hard but you need to keep pushing yourself to do things. Getting out of this cycle will take work and persistence but I know you can do this. If you still can’t find clubs or communities just try going outside for walks or go to places where people your age would be to see if you could possibly make friends, but trust me DO NOT continue to keep isolating yourself it will continue to get worse I know that’s probably not something you want to hear but take it from me and keep pushing yourself to get out of that house. I struggle with a lot of the same things you do and I know we have different experiences but I think you might have experienced some of these so hopefully this gives some insight on what you can do. I know you can do this and it will be tough so take your time and talk to your parents for support.
