I think my daughter (7) has ocd. She gets very anxious about fires happening or about me or dh dying, sometimes it can take over an hour to select her at night if she's very hysterical. She has to have everything just so at bedtime- her cupboards have to be open, her duvet has to be lying completely flat, the door has to be slightly open at the right angle etc. If we kiss her it has to be an even not an odd number of kisses.
We've kind of gone along with it so far thinking it's probably just a phase but just lately there's been an acceleration in it. She won't let me touch her because I'm "dirty", she's very fixated on her appearance- her hair has to be done 20 or 30 times before we leave the house and she gets hysterical about it not being right. Her wrists are covered in self inflicted scratches. The hardest thing has been her clothes. Thankfully she will wear her school uniform but normal tops she keeps pulling them down at the front, sometimes I even hear them ripping and she says hysterically "I can't wear this it shows my boobs!" and the top is flung off. Same with trousers. It's a nightmare if we have to go out anywhere. She's also extremely aggressive- shouting horrible things and attacking us physically over the slightest thing.
It's causing so much stress and arguments, we just can't deal with it anymore on our own.
