I have trouble being social and get nerves in bigger groups of people that some i dont know any tips on getting more confident
Well its a big difference if u feel bad around other people, but you can force yourself to be social, or if being around people just make you anxious, but you want to socialize with them. If its a first case then exposition therapy is just a cope, of course you can raise your social skills, but you will hate doing it the same for the rest of your life, and if you are closer to option two, so you feel the need of socializing with other people, but their presence makes you anxious then exposition therapy is actually a great idea, you can also combine it with learning basics of psychology alongside with developing your metacognition, both internal and external. That's something that will allow you to develop cognitive empathy which is superior to the instinctive one, but even as an empath you can use it alongside your deafult one. And when you master social metacognition social interactions are no longer scary, because they become so boringly predictable that being scared of them is impossible. But to achieve that you need to diagnose people around you, that's why you need metacognition, bcs if u cant even look at your own mind from the third perspective, you will never be able to understand other people psychology.
