I have had depersonailzation since I was about 12 years old and it comes and goes over the years. I am trying to find out how I got this. Is it hereditary or does something cause this from childhood? I wasn't abused or anything. my parents got divorced when i was really young and that was depressing to me, i would cry alot. also i noticed when something really horrible happens I get my DP back. I am on anti depressant. any help would be appreciated. thanks
