Sounds to me like you're having some bad anxiety attacks. That's how they used to hit me, when I was having them. They'd just "take" me -- overwhelm me, like you describe. There wasn't much I could do about it.

You need to talk to your doctor -- perhaps have him refer you to a good therapist and have him show you how to cope with these and perhaps prescribe some medication to help you deal. These can be quite debilitating at times especially if they hit at very inconvenient times! I remember having one while I was checking out at the grocery store -- I had loads of groceries on the line, and here I am having a severe anxiety attack!!! I began deep breathing, etc., but when I was all checked out, she wanted her money -- and I couldn't even write the check out! So all I could do was sign my name to the check (you could BARELY read it -- and the check out girl had to make the rest of it out! I was SOOO embarrassed! I got out of the store as quickly as I could, and didn't go back for a long time!

Talk to your doctor. He can help. I wish you the very best -- and please keep us updated on your progress, will you? God bless and take care of yourself. Hugs, Lee
