Gaming is okay as long as it is not excessive, if you are using it to avoid real life people, then it's probably not the best idea. What do you enjoy doing? Is there a club or activity you could join to increase your social circle? Social anxiety is actually fairly common, unfortunately, the more you avoid people the harder it is to get back. So my suggestion would be to use gaming in moderation and try to spend time with people also. The more we avoid the things we are anxious about, the bigger they become. And to be perfectly honest, I think most of us are scared of what other people think but in reality they are not being as judgmental as we think they are.

Are you seeing a therapist? It might help to counter some of your negative self-talk with something more positive.

Hang in there! Hope this helps!
