I feel the need to clarify this. DID is only 1 of the many forms of dissociative disorders. What you are describing about having amnesia is also another form of dissociative disorder. Not DID. DID means you have alternate personalities when you dissociate, whereas other forms of dissociative disorders include some form of amnesia, depersonalization, or derealization. If you have a dissociative disorder, yet no alters, its most likely DDNOS. Unless the doctor specifies which form you have. DID does NOT mean "Dissociative disorder" it is merely a TYPE of it.

Also, you can have BPD without rage and cutting. There are 9 criteria and you only have to fit into 5 of them to have the diagnosis. One of them is dissociation when stressed out.

What you are experiencing, sounds to me like PTSD.
