A little bit more on exercise. I find that lifting weights helps me burn some fat. Muscle actually burns fat. It increases your metabolism. You will be more toned, and have more energy also. You dont need to lift heavy weights. Just two small light ones, do the reps properly and slowly. Best in combo with aerobic exercise though, but it is really important to take care of your muscles also. And drink a lot of water☺
And now, take this from a non-believer, if the god you believe in is the god of love, why would he condemn you to go to hell? You have an illness, and a god of love and FORGIVENESS would not punish you for that. That is what I was taught in Sunday - school when I was a little girl at least.
Not for religious debate, just giving my understanding of the Christian faith, since this seems to be on your mind.
