I imagine your doctor is concerned about your health and that is why he is suggesting diet pills. One of my dear friends at work weighs about what you weigh and is 5 ft. 3 in. She is on high-blood pressure medicine because of it and has more illnesses related to her weight than you can imagine. I would love to see her lose weight just so she will be healthier and possibly live longer and that's why I make sure we get out and walk everyday at work.
I'm not sure if you are saying you would like to lose weight or are upset because people aren't accepting of you at the weight you are.
