well, multiple personality is called D.I.D. now (dissociative identity disorder) and it stems from childhood abuse... so it would be something that you have had for ever.. has this happened before? or is it just something new?

you can dissociate without having D.I.D. , everyone does it to an extent at times...

but i can relate with your post, hopefully more people will have more advice and words...

welcome to the forums, i hope that you are able to find some answers and find your time spent here helpful
