Coping with any disorder has it's difficulties, for sure.
Dissociative Identity Disorder in itself reveals something traumatic to you occurred (not saying it would be traumatic to everyone...and for others it may have been too much and they would have died!)
Consider your brain's ability to segment, split off, create another personality to cope, as a gift? I know that's hard to do... but keep telling yourself how intelligent an act this was!
You are alive because of your ability to block off the trauma...and keep living.
Now comes the hard work of training your brain that you don't need the protection anymore, that you are ready to analyze the trauma and dispense with the divisions created.
