im back! need support...

I was a member here a few years ago and lost a lot of weight. I got pregnant and just had my baby (2 months) and now need to lose weight. After I had my baby instead of losing weight I gained!!! I was on bed rest for a month and it was the worst. Now I have been trying to lose weight and find it so hard. I get discouraged the weight isn't coming off. I went to the dr and he told me to tr a 1200 calories for 3 months and then go back for more test. Ahhhh...Anyways today is day 1 hopefully this works. Thanks for reading
