Controversial Opinion but one thing that I learned in the last few months of 2023 was to not accommodate my social anxiety at any cost. If you're someone like me, whose social anxiety is caused by fear of messing up and just not being used to socializing, then this is for you. Do not indulge or adapt to your anxiety, instead just do it. I know it seems ridiculous, but really you have to just expose yourself to what you're anxious and scared of, which in this case is socializing or basically doing anything publicly.
Exposure=Knowledge=practice=confidence=less anxiety because once you're exposed to your fear, it'll get easier. Sure, it may takes weeks, months and maybe even years, but you will eventually gain confidence and get better at it. For instance, let's say you suck at doing pull ups. But you practice it for 30 days and eventually you will see improvements. It's the same thing with social behavior, you won't get better at it if you don't participate in socializing. You have to show up, even if it's just for 5 minutes, even if it's just walking to the grocery shop. You need little steps to achieve confidence and fuck social anxiety up. If your anxiety is telling you not to do it because you'll look dumb or ugly or whatever, it's lying to you. You need to do it anyways. Literally cannot explain this enough, do it anyways, even if you're bad at it, even if you don't know how to do it. Do it anyways.
