I can remember a time as a teenager and in my 20's when I was pretty extroverted and actually enjoyed being around people. I now realise that I was masking and due to so many bad and traumatic experiences both in friendship and relationships that I have really isolated myself and can't stand socialising now. I hate being like this but I realise it's some kind of burn out and I'm going to have to try to work through things. Has this happened to anyone else ?
