Since I was 6, I have struggled with anorexia, bulimia, OCD and body dismorphia disorder.
It has been a lifelong battle for me and I had assumed it was 'normal' and never thought anything of it. Three months ago I decided that this was not normal, and was sick of going through life hating myself and my body, so I went into treatment.
At first it was difficult, but eventually I realized why I really DID need treatment.
It's still a struggle every day, and there are good days and bad days. But all I have to tell others is to do what you need to do for YOURSELF. Don't feel guilty for putting yourself before others. You deserve to be happy and free from anything weighing you down.
I went 13 years hating my body to extreme extents. Respect your body and listen to it and give it what it wants. There's so much more to life than this empty superficial expectation of media's 'desirable' size 0.
