I don't know what's happening to me but I obsess and panic and question my own exsistence all the time. I looked into depersonalisation,o.c.d and found similarities but that doesn't make it go away. I had an abusive childhood and my partner thinks I'm suffering from p.t.s,but I left my childhood years ago....I just seem to keep feeling all the feelings I felt when I was younger but applying different reasons to them. It's almost like I convince myself I don't exist anymore or that I can't fathom out my being. please if anybody can relate to this or share their experience it would help me greatly. I get so stuck in this and then consider turning myself off.
