Hi, Jeanie...nice to meet you!
The identical thing happened to me - I've been seeing my pdoc for around 12 years or so - diagnosed Major Depression Recurrent. Have been taking Zoloft & Depakote.
I'm currently on short-term disability from work due to an episode I just can't seem to get out of, so pdoc said when he put me on Depakote he knew I was Bipolar (just didn't tell me) and since nothing else has helped lately, I've been put on Lamictal as well.
Praying this will get both of us feeling MUCH better!!!
