I had the same thing with weight gain from Zoloft. I was at a normal bmi when I went on Zoloft and gained about 75 lbs in that year. That stopped really working for me and I was put on Paxil and again I gained more weight. These meds work for sure for depression and anxiety, and ppl have sometimes have no choice to be on them. For me it ended up causing more problems with the amt of wt I put on.
