Sighted people can glance in the mirror to check if their hair looks good, whereas I have to seek confirmation from people around me and hope to God they are being honest.
They'd comment on my portion size which is particularly damaging when you can't actually see the plate.
As I reapplied my lipgloss, I had no idea what the girls around me looked like: whether they had nicer hair, better makeup or clearer skin than me.
The difficulty was I couldn't talk about my body image issues as I was petrified I wouldn't be taken seriously.
