Seroquel and antidepressents

was on seroquel for a few days, after trying several other antidepressants which all had led to, weight gain, no sex drive (zoloft) heart "vibrations" and other side effects more harmful than helpful. but, the seroquel put me in a comotose, translike state. could not move off the couch, could not eat nor talk, a total zombie. stopped immediately, it took about a week for it to get out of my system. I am on zoloft again 50 mg. still no sex drive whatsoever, slight weight gain. but having no sex drive is the ultimate worst, yet I don't miss it at all when it was once the highlight of my marriage. sad to say marriage iss on the rocks, due to this minor problem. would love to go off it,, but i am too stressed. have tried so many drugs i can't keep track. do not want to gain weight or have no sex life, any suggestions on an antidepressant with no side effects? I am also going through my changes, ai am 50, which does not help.
