Trying to OD on antidepressants is likey the fastest way to get a ticket for the ER, is almost impossible to die with them. The are "almost" no cases of death due to SSRI (i'm assuming the meds the doctor put you on) or antidepressants in general, the maximum you'll get probably is serotonin syndrom and I assure you that is not very plesant. If your doctor prescibed recently this meds to you, just give them a little time and maybe they'll work (give them the benefit of the doubt).
