alikat et al,
It does indeed sound like you may want to bring up meds when you next see your doctor. Are you working with a pdoc and therapist? If you have both and they understand dissociative disorders they can help all of you get through times like these. That's why we pay 'em the big bucks!
Seriously, please consider making some notes for the crew about how the lack of internal quiet is making it exhausting for you.
You are not crazy. You are dealing with PTSD and DID in addition to other things. The healing can feel like crazy but it is not.
I think that you are a very loving wise mother to know that right now you are not able to be full time mom. Your children are lucky to be so loved. He's the crazy one for not speaking respectfully about you in front of the children.
