My Definition... please add one of your own.
Let me tell you from personal experience that it's not about alters. That's the least of it. It's about suffering from pseudoseizures, violent flashbacks, insane-like mood swings and being so dissociated it's hard to drive and impossible to remember much of anything on a day to day basis. It's as if I did not have a childhood - and at least half of my life is missing. It's being told, by other parts of me, what those 16 years of childhood were like and somehow wanting to remember those years even though they were filled with terror and pain - something is better than nothing - or is it? It's being thought of as a freak in elementary school and being diagnosed with schizophrenia when you don't have it, because no one can comprehend what is really going on. It's hiding from life as much as possible, just so I can cope from day to day. It's living with Mother and Father introjects in my head - endlessly attacking me even now I am an adult. It's living in a deep depression and unable to climb out. It's wondering - will I ever be able to function normally.
That's what DID is like for me.
