Thanks for the answers everybody.

I have a few more questions.

Would it be better for me to call my psychiatrist and ask if they do any evaluation for dissociative disorders or should I ask him during my next appointment? I only get to see him every three months.

How long does a full evaluation take, especially when it comes to seeing if something else is going on? I'm afraid of not getting enough hours at work, so I want to be prepared.

Also, just out of curiosity: Do psychiatrist normally diagnose dissociative disorders or do therapist diagnose them?
