Try not to be so down on yourself(I know,easier said than done)... we all have slows. It will come off,if you follow drs orders.
Not everyone loses at the same rate. If you can't exercise yet, WALK... Walking is what helped me the
most and still does! It will get better. Try tracking all your meals on myfitnesspal.com That's what Iuse.It helps me keep on track... Good luck
