You are definitely right about that, those thoughts are very deep and they seem so real. I think it takes a lot of effort and constantly remembering those thoughts dont have to rule us, hopefully in time they will be fewer and farther between. I have really been pushing myself lately and having good results. it's still really stressful but I think it is getting better.
try to do it in a relatively safe environment-if you are in school that can be intimidating-coming in contact with people of all ages seems a lot easier. try to find people you have something in common with, then you can make small talk without feeling too awkward. hobbies are a good place to start
