My doc gave me Buspar (buspirone) since 2 months now and it's not working. Also proved antidepressants like zoloft, efexor, cymbalta, prozac, wellbutrin, paxil?

Antidepressants. What is your question, it is confusing.Have you been all the antidepressants you mentioned or would like to try.You should consult your psychiatrist and discuss your concern.
Dont quit treatment. I am assuming that you had the dose of Buspar adjusted appropriately and you took it for 6 to 8 weeks. Have you tried pristiq, viibryd, (vilazodone hydrochloride) lexapro, Celexa ? There is a group of antidepressants known as maois and also tricyclics that may help. There is also magnetic brain stimulation. Ask your psychiatrist.
