I have a serious problem when I am alone with a single person I am so witty and can talk with people for hours and when I am in a group maybe it's something unconscious that I have about my looks or relevancy when I am with multiple people that literally puts a lot of pain in my head and it goes blank and no matter how much I push it at that moment it does not go back to normal until like an hour or too . How do I practice overcoming this because sometimes even when I start touching the waters and trying to practice talking in groups sometimes it goes blank . And yes for some reason I can do public speaking easily, maybe it's because ik i am well dressed well groomed but I don't wanna be that way , I just want to be chill in the skin
