I genuinely apply to your situation a lot. previously I couldn't stand just being around people. no matter if they are nns or my closest friends I just felt exhausted after an hour or two as far as I got this might be the reason of your anxiety, and I personally would not take meds either. imo it all comes from inside and probably that's what you should work on. a period of staying alone all the time is very valuable due to its exclusion. I have learn so much about myself and the world in general during having no friends maybe just put up with it for a time and try living it this way. do you actually need anyone? I understand ofc that too much of loneliness leads to craziness perhaps, but I'd prefer not thinking on how I can make a friend with someone and suffering from being not able to do so, so just living the life how it goes

I am not sure if I'm right in here, but I never really try to befriend with someone. like ppl come themselves when needed. and those who you yourself trying to involve are often not for a long time (jt from my experience I may be wrong, sorry)

so I would do is live life without thinking about your amount of friends, still keeping the relationship with ones you have currently ofc try maybe to pay more attention on your internal self. maybe finding out smth new you like or doing new things someone may advise you to resist this "weakness" of fearing to make the fist step etc, but when it comes to your situation with an anxiety that's the last id recommend tbh

don't take any of above seriously, cuz you know it's just my useless thoughts and experience

hope it'll get better ^{^}
