I've always had weight problems and have yo-yo dieted resulting in up and down weight loss and gain over the years. About 4 years ago I experienced some health problems that caused me to gain weight. After surgery the doctor found a few more issues that contributed to my weight gain and my lack of energy. I've been on medicine for about 3 years and started slowly to get the weight off. I added exercise to a cleaner diet and now the weight is coming off a little faster. Unfortunately I still don't have a lot of stamina. I am improving but it’s frustrating since I know my body could take more but my heart can’t take it. Learning to be patient with myself is hard, especially since I’m not the most patient person in the world anyway, but I know if I keep a consistent workout schedule the stamina will improve over time.
