Need inspiration to lose weight?

I had bleeding ulcers from taking years of Excedrin for migraines and didn't realize it until I became anemic and lost my energy. I ended up gaining 35 lbs from the loss of energy. I had to go to the emergency room to get a transfusion and also found out I had high blood pressure and an irregular hear beat. Ever since I've taken my heart medication, I hardly ever get migraines anymore, and I also have gotten my heart beat to a better rhythm. I just can't get my weight down, because I'm stuck in a whirlwind of "heaviness" that's slowing me down, and it only depresses me. I can't take diet pills because of my medications. I don't know what to do!
