Telling someone with depression to 'just get over it and be happy' is like telling someone with a broken leg to run to a hospital
Telling someone with an eating disorder to 'just eat' is like telling someone with claustrophobia to get inside a small cupboard and lock the door
Telling someone who self-harms to 'just stop doing it' is like telling a drug addict to sit in a room full of drugs and touch nothing
