I'm physically healthy and my mind is somewhat stable from medication. I used to be overweight, pre-diabetic, and had high blood pressure. I lost the excess weight and am healthy now. I do believe your mind is affected by one's physical health. I don't think I would be as happy if I was physically unhealthy still. I was extremely unhappy and miserable when I was fat. I was extremely stressed out by my situation but after going through hell and back I am doing fine now. I eat at McDonald's so don't always eat that healthy. But, I try to eat salads and don't drink soda usually. I also walk everywhere and am now trying to take the stairs instead of the elevator or escalator. It has been helping me. I feel great!!
