Did he/she give you a reason that they preferred to use an anti-seizure medication rather than convention treatment with another antidepressant?

Just that the Wellbutrin I have been in for 15 yrs stopped working! I wake up every morning very depressed, but I never miss work!! She say’s I’m not Bipolar, but since the Prozac made me feel weird, I guess she would try this other one

I do have a bipolar 2 diagnosis, which I believe to be accurate, so my comment needs to be placed in that context.

My response to antidepressants was horrific. They flipped me upside down and amplified my depression so severely that I landed in the hospital before anyone realized what was going on. My psychiatrist recommended Lamotrigine and I decided to give it a try. The results have been remarkable. I was nearing 60 when I started taking it, and a lifetime of cyclical depression simply went away. I've not suffered a single bout for over a year-and-a-half now. I used to have several bad patches every year when I'd get deeply depressed. Emotionally, my life is better than it has ever been

Lamotrigine gets mixed results, from what I've seen. It works for some, not for others. But this is true of every drug used to treat depression. I'd say if antidepressants weren't helping, give it a try. It takes a bit of time to kick in, and my dosage is significantly higher than 25 mg, which has to be considered as well. But if it works, it could be a lifesaver for you as it has been for me.
