Late comment is late, but;
DID is not the problem. Having alters is not the problem. The problem was the rape that caused the DID, and the co-morbid PTSD. The alters themselves can do quite a bit to hurt the host, that's true. But they can heal and accept the abuse without integrating. In some cases, yes, accepting the abuse causes automatic integration. In other cases, the host has had DID since they were two years old. Their brain is literally wired differently because of the affects of the abuse during key developmental stages. This wiring allowed for the DID in the first place, and it won't change. So it's entirely possible that integration won't occur.
And being proud of having DID means one is proud of having SURVIVED the abuse. Am I proud of being abused? Fuck no. Am I proud (or at least relieved) that my mind managed to keep me alive by splitting? Well, it's better than being dead, I'd like to think.
