Most of your ailments are due to your massive weight. You need to start a 1200 calorie restricted diet, with a nutritionist. You also do qualify for gastric bypass, which could svae your life. If you don't take dramatic changes in your life, you will pass away in 5 years, and that will be a shame. Look at yourself in the mirror, and if you are ready to die, keep doing what you are doing, you will be there soon enough. I highly encourage you to change your life. I have seen patients much worse than you get better.
