I am a 17 year old female, diagnosed with PTSD and depression following sexual trauma a few years ago. People close to me keep telling me I'm not myself around them, as I go through 'episodes' of extreme self destructiveness, anger, fear and suicidal tendencies - although I feel exactly like myself during these episodes, and I have no significant memory loss (except surrounding the trauma). Is it possible that I have Dissociative Identity Disorder?
