I am recovering from anorexia and body dysmorphic disorder and I wanted to share some body image tips with everyone. These may or may not work for you - I am writing from personal experience.
1. Comparison is your enemy. It would be physically impossible for you to have the exact same body as someone else, and people come in all shapes and sizes. Avoid comparing yourself to others at all costs.
2. You are powerful. Story: I do not naturally have a thigh gap. I was ashamed of my legs for years. I'd wear baggy jeans and hoodies to hide them. But then, I saw a post on instagram featuring a girl whose thighs didn't fit into a pair of jeans, and the caption said, 'My thighs are just too powerful for these jeans.' and ever since I read that, my attitude towards my legs changed. I have legs that allow me to walk, swim, and enjoy life. I love them.
3. Surround yourself with positive people. Don't hang out with people that comment on your weight and body. Follow people that make you feel good about yourself on social media. Unfollow anyone who doesn't.
4. Listen to good music. Often. And dance to it too. Dancing made me feel cool (though I'm a total nerd but - hey - nerds can be cool too). I felt proud to be in my body and happy to be able to move it in a way that felt good. Especially to good music.
Anyways, I hope these are at least slightly useful.
