That i have a dissociative disorder?

I'm a sufferer of major depression, generalized anxiety, dissociation, and mood disorders. I'm mainly asking this question to see how normal it is to have panic attacks, and dissociations. If you don't know what dissociation is: http://www.mentalhealthamerica.net/conditions/dissociation-and-dissociative-disorders

I appear to have psychogenic amnesia. I don't remember certain memories, and when I do I often dissociate for a brief time, and am unable to remember the trigger, the memory, or anything else while I was in the dissociated state.
