I have recently been diagnosed as being bi-polar by my psychologist. I show all the signs of it I explode out of nowhere get freaked out really easily and have severe mood swings. But he also says I have dissasociation disorder or depersonalization. My question is how did I get this disorder in the first place? its really scary Ill be in my room or sitting in class and I won;t recognize anything or anyone everything will look weird or foreighn especially my room. The other day it happened and I was watching TV and I couldn't realize what I was watching.I didn't even know what I was looking at the TV didn't look real. All this stuff happens at night in the day I am normal have a girlfriend I have a lot of friends but at night I freak out it starts at about 6 oclock. everything just feels different and weird and my parents don't look familiar and I feel like Im disconnected from everyone. What caused this and my bi-polar. No one in my family has it And I come from a great family no abuse we have money everything is nice. I learned dissasociation comes from post tramatic stres blocking things out and I realized that I can;t remember 2 days ago my mermorys like gone. But what could I be blocking out if everything seems ok. I appologize for the length of this post. Thanks!
