exercise fail

For the past almost month I have been exercising. Well as much as the doctors and my husband will let me. I do squats and ab exercises mainly. My husband has been a great motivator and I actually like working out with him. But..... this weekend I over did it and passed out. I was starting to fill my heart thumping hard but figured it would settle and kept going. Well minutes later I was OUT. Needless to say my husband says no more exercise for me. I get extremely frustrated because I want to do this and I want to have a healthy in shape body for transplant. Instead I feel fat and lazy because of the retention and lack of daily exercise. It is really starting to bother me. I am use to being a small string bean gal and this whole big belly thing is getting old. So for now I will rest and maybe pick it back up once I speak to my doctors....
