Can Stopped Intake Of Zoloft Cause Depression, Reduced Weight Loss And Bloating?

I was 120 pounds and then I started taking zoloft, three months later i weighed 135 and kept taking the zoloft for another month. I felt more depressed than ever so I stopped taking the zoloft 2 weeks ago and started changing my eating habits but I haven't noticed any weight loss and I feel bloated! I usually lose weight very quickly, is my metabolism ruined?
