According to what I read - a person must have some sort of predisposition in his/her brain that causes them to dissciociate- otherwise they will have some other mental illness instead. But I guess the common factor is that DID is not a good thing and that it is caused by something that is unhealthy .However severe it is for that individual I guess varies - but something happened to them to cause it.
In my particular case I was sexually mo****** .This I know and have regular memories of before I ever entered the mental heath arena . Now I'm probing deeper to see if there was anything else - or if it was all the ab*** that I remember that did it. I know for a fact that I was not born this way - something tramatic happened to me to make me tjis way ,and I rember some of it - and maybet as " MYSELFSAIDI just need to attach emotion to it all because they are just memories to me - I feel nothing when I think of it, . And to me- what I remember was of sickening severity enough for any little boy to expierence I would think to cause DID.
