Argh,I am sorry to read of your memory problems. A thought crossed my mind when I read your post and I am going to post a link Dissociative Amnesia.

I have not experienced memory loss in the manner you have and I can only imagine how frightened you must be. What is your Dr. offering you for therapy ?
If you want to read you older threads here in the forum just click on your name Argh and you will find links to your last 10 posts.
Thinking of you,
Kitt
