I just want feel beautiful.

Lately I've been so insecure about myself to my looks to my weight. I truly hate it. I never feel good about myself anymore. No matter how hard I try to eat right it's like my depression takes control and makes me eat terribly. I don't know why but I truly try so hard. But I just don't know how to shake this. I need advice on making better choices, and how to stick to it.
