People with eating disorders, how did you manage to overcome it?

I’m exhausted. I can’t eat anymore. I’m scared to go outside because I feel like people will think I’m ugly. I’m afraid to go shopping with my friends because I’m scared the clothes won’t fit me. I smell coffee just to suppress my appetite. I’m even afraid to take a shower because I can’t stand looking at my own body. I’ve become so burned out that I can barely get out of bed, and I’m terrified of food.
How did you get through this?
