You need to go see your psychiatrist, stat, since you sound like you're about to lose it. Go back on what has worked before, until you've been stable for a while (I believe a minimum of 3 months completely symptom free before starting a taper is a general rule, but don't quote me on that). After that, you'll have to see. Some people, who are really good at telling when an episode is coming, are able to start meds, usually an antipsychotic or atypical antipsychotic, when they need to. Some people report using things like zyprexa for a short while, which works for them to abort an episode, although they might still be taking their normal mood stabilizers in between episodes.
But that's long term. You need to do something RIGHT NOW, because you sound like you are rapidly approaching crisis, and remember that it will take time to get an appointment and that it will take even more time for any treatment to work. Don't wait until you can't stand it any more, because then you will have to keep on standing it (been there, done that, not fun).
