Postpartum depression and weight gain

After I had my little one I got PPD and was put on Zoloft. Well within 6 months I gained 35 lbs. I thought oh it's just some weight I'll get back into the swing of things at work and loose it. Fast forward and two years have passed and I'm still the same weight even after trying to diet. Also we've been trying for baby #2 going on 4 months now with no luck. Today my doctor has switched my meds and says no trying for baby until I get down to my initial postpartum weight before my Zoloft weight gain. Here's to getting back to 170. I'm 210 right now so I've got a way to go but baby #2 is on the line. Starting a new job, diet and exercise plan all at the same time, this should be interesting.
