I have DID. Trauma happened in my childhood as well. It was horrible. I have at least 10 personalities and one of them integrated with me and she is extremely dangerous. The age ranges from 2- 350 years young. Why 350 you are wondering? Well, one of my personalities is a Martian! I guess they live much longer. Each of my personalities has a different voice. I have two kid personalities and a few adult ones. Others are weird like I have a bird, a robot and someone who gets confused and who can't complete a sentence!
