Need some advice.

I'm almost 20 weeks with my first baby and I've gained 13 lbs. I was overweight to begin with and the weight has caused me to cross over into the obese bmi range. I carry my weight very well, have an hourglass shape with a 36H bra size. I'm 29 years old.

I have a full time sedentary desk job, but i make $54/hour and it is a very stressful job. Ever since I got pregnant my husband has been riding me about the things I eat. I feel like he expects me to be perfect and I got so depressed over it during this pregnancy that I had to be placed on an antidepressant.

I get that he wants me to be healthy, but I just can't be perfect at everything in life. Eating is my one vice. And he holds me to a different standard than he holds himself. Example: he can have a Coke, but I can't because I'm the one that's pregnant and it could cause an insulin spike in the baby. I feel so overwhelmed with him expecting me to be perfect that I don't even want my baby at times.
