someone close to me has been diagnosed with OCD. it's a horrifying and painful disease to deal with. People think it's quirky or cute, but do you know how painful it is to have a constant screaming in your head unless you touch the fifth tile down the hall with the left side of your foot before your right seven times in a row before opening and closing the dor three times? even worse is, unlike other mental diseases, you're aware that there is something terribly wrong with you. You feel trapped in your own body as you're forced to go through emotions again and again. I've stayed up nights with her in my arms, sobbing because she can't face the public every day, knowing that they might see her as a freak.
tl;dr OCD is a painful, scary disease, and I'm speaking from experience.
inb4 hurr durr I have OCD
