Cassiesmom- correct me if I am wrong- but a mental situation is NOT considered a " pre- existing" condition is it? Considering its not predictable etc.. Also- a panic disorder- can be caused temporarily ... Also- you are totally right about the b complex helping tremendously. When I was going through all those hormone changes, my doctor told me to take it too. ( As well as you.. lol). I could tell if I didnt take it- it sure did help.
