In layman’s terms, OCD is the chain-letter-posts of the mind. It’s like having one of those “if you do not reblog this, you’re family will die” posts pop up in your mind, but instead of reblogging or reposting, you have to flick a light switch or pick something up that you just put down.
But with much higher stakes than ‘just in case’. Because your disorder makes you terrified that it might be true, no matter how unlikely it is.
Just in case.
