Zoloft and Weight Gain

Hello all, I'd like to share my story and hear if there are any similar occurrences. I was always thin and didn't have to work hard at it. I've been on Zoloft for 11 months now. In that time I've gained roughly 2lb per month. At first my appetite didn't increase. I dont eat much to begin with and ruled out eating patterns. My activity levels remained pretty sedentary or low. In total now I've gained 22 lbs on zoloft. Seeing myself gain weight for the first time ever appeared shocking. I said the pros of the medicine outweighed the cons and they did. Until now at 22 lb heavier I have gained weight everywhere. Especially on the stomach, legs, arms, neck, and back. Fat rolls are overlapping and clothing is constantly getting too small. Last night I looked in the mirror and just felt disgusting. With medical guidance im now switching to a different class of medications that shouldn't cause wright gain. But will the weight from zoloft go away on its own the same way it came? It's been insane to now see just how much energy I lack, I mean damn it's even become hard to put on shoes. Going from a size 1, or 3 to a 6+has been a very difficult road especially since I need the medicine.
