First, there is no such thing as a nervous breakdown -- that's not a medical term. You don't mention if you're seeing a psychologist in conjunction with your medication. You don't mention if you're seeing a psychiatrist or a general doc, as lithium is generally used with psychoses, not what you've listed. It's possible your doc is stumped and moving to atypical answers. The thing is, if you're suffering that badly, it doesn't sound like the meds you're on are working. Rather than continually adding other meds, the problem may be you need a different antidepressant.
