I hope you don't think I was rejecting the possibility of DID, because I absolutely was not. I know some people resist the idea, or don't "believe" in it, and that is not me at all. I just wanted to present different possibilities. It sounds like you've been very diligent in exploring medical reasons, and you are absolutely right to be exploring possible psych reasons too! People who have been psychologically damaged to the point of DID often have physical problems as well. There are some physical challenges that I have. Many of them are explainable as a result of abuse, some of them are symptoms that cannot be specifically diagnosed or treated, and may be a combination of physical and psychological damage.
And I don't think you talk too much! It IS important what you have to say!!! (if okay)
