It totally sucks to have this control our whole lives so you are not alone.
I had to go to pdoc Monday and get a Lithium increase, and more sleeping pills as I had the manic stuff you noted above.
He said it is really common when Spring starts to come for us to see an increase in symptoms. I know meds aren't the best answer, and who wants to take a bunch of pills, but I would call again and let them know the buspar has stopped working.
Sorry you feel this way.
