i need to lose four stone. but its not just the losing weight i NEED to get fit and keep the weight off. i do a lot of walking as i dont drive, but i want to start running or jogging etc but i feel too embarrassed to go running, incase i get laughed at by people i pass etc. its making me quite down hearted. i felt so emotionally ready but now im chickening out. i scared that if im laughed at, it will make me give up altogether.
