The episodes with "fainting" sound a lot like seizures to me, especially if you are convulsing. I have been treated for seizures following the removal of a brain cancer, and they check me for (and I have felt) a lot of your symptoms : headache, clenching teeth, dizziness, lightheadedness, tremors, changes to your vision, and tingling (mine was in my arm). I would check with a neurologist who focuses of epilepsy. You might not actually have epilepsy, but you seem to be seizing and maybe they could put you on the right medicines (i take control release lamictal).
I'm surprised that none of the doctors has recommended changing your depression meds. On and off since 2002 I have taken Paxil, Zoloft, and something else I don't remember what it was called, and they all had side effects. One made me edgy and nervous all the time, one made me "zombie", one made me have my regular depression gone but my really bad depression phases were even worse. I'm on Lexapro now, and I think its the best one so far - even though when the doc tried to increase it it gave me sudden fainting/lightheadedness, so i switched back to the lower dosage. They all kind of work differently for different people. A friend just started Lexapro to deal with a divocce and she says it makes her hungry and tired, which I don't find at all. You have to find the ones that work for you, which *****, but if you find them its so worth it,
Good luck! I've been through some of your problems, and I can imagine how crappy you must feel. I hope you find your answers.
