I Am Researching Antidepressant Medications And Am Debating On Xanax,

I am researching antidepressant medications and am debating on Xanax, Wellbutrin or cymbals. My dr. Is ok with either of them. I tried viibryd and really didn't feel that it helped at all. I have been off medicatin for almost 3 weeks now, but feel I need something. I feel so sad, anxious and find no joy in every day things anymore. What do you suggest? Please help me find something that will make he feel happy again. Thank you.
