Lamictal did nothing for me. I'm not sure if I ever tried depakote. I would suggest you give up on stuff that is not working. I would further suggest that you give up, for now, on meds directed at bipolar disorder. Start trying meds specifically aimed at depression. I know they say antidepressives can trigger mania, but depression is so painful, it's worth the risk, IMHO.

Tricylics work for me. Also Remeron (mirtazepine), which is chemically similar. (It's a quadricyclic.) Not that any drug us a cure. But amitriptyline made a dramatic improvement, even though I was convinced it wouldn't help.

I believe that most people with depression have something going on other than inside the brain's neurochemistry. I believe that most depressed people have an approach to life that is not working for them. A lot of the components of that may be things that you literally can't change . . . things that have become hard-wired. But see what you could change . . . some circumstance that you could alter. For instance, I learned that I could feel a lot better by not working nights.

There may be some responsibility that you need to let go of. Of course, I know you do need to care for your child. Maybe there is something else you could give up. Or maybe you need to add something. Going back to school greatly helped me a few times. (I went in and out of school a lot.)
