I’ve tried everything.

As of now I’m unhappy with my weight. I’m over weight for my age and I don’t know how to fix it. I’ve tried different diets, exercises, yoga, sports, relaxations, pretty much everything! But there’s nothing that really seemed to work. Does anyone have any advice on how to lose weight? (I’m saying this partially because I don’t like how I look and partially because I’m just not healthy.) 😕
