Hi there,
I am sorry that you are experiencing these symptoms.
a couple of questions for you:
ARe you possibly reaching menopause?
they say we can start having symptoms for 10 years prior.
ARe you bipolar 1 or 2.
Insomnia will trigger mania faster than stress will,
you do need to call your pdoc to get something to make you sleep.
Have you had a good physical lately to rule out any possible thyroid involvement?

I once started taking prozac for obcessive compulsive skin picking. Sent me full blown manic...I bought 2 cars in 3 weeks...$5K mistake...awful.
WElbutrin is a safe antidepressant...
have you tried this before? how about provigil?
I am sorry this is so hard...
((((HUGS)))
