Best Diet Plans?

Elizabeth
Hey guys. I've been told I am overweight. I have tried almost every diet out there and they don't work. I've tried different types of pills, working out and playing sports. I am 23 and 5' 1" and I weigh 150 (last time I checked) I hate it so much. I don't feel attractive and sexy like I used to. Any ideas on how to lose all this weight??
