Hi Peaches, I didn't know I had did until I was in my 40's and retired from teaching. Yes it is possible to be high functioning my ten alters blended together well so people really didn't notice. I have epilepsy so even family members put off memory problems to that. I now have a new career working with the elderly and sometimes they help me remember little things like forgotten names etc. I only have one alter left and we have problems from time to time but not at work.
