I am just about to turn 29, I have been overweight as long as I can remember and its going up and up. I am now about 24 stone and my BMI is 60, as I am only 5 foot 3. I have PCOS, underactive thyroid and depression. I have tried various options, lighterlife, weight loss tablets, diet, exercise and therapy but I just can't seem to manage it. I have considered gastric band but I am scared of this option, but also can't see myself being successful alone. can anyone help or give advice?
