Help?

Okay, so I'm writing a story where the main character has symmetry OCD. I'm trying to find as much info on symmetry OCD as possible, but almost all websites I've seen have the information over and over. I'm not learning anything new, and I'm still missing so much! If anyone knows any sites or information on OCD, please post everything you know here! I really, really need help! Also, symmetry OCD only, please. I don't want any information on contamination OCD or sexual OCD. Just symmetry, order, and perfection. Those all kind of go hand-in-hand when it comes to OCD. Here's what I know so far:
People with symmetry OCD have a need for perfection
OCD does NOT mean that the person is crazy
People with symmetry OCD will get very irritated and have an outburst if anything is even minorly off balance

By the way, I'm looking for information on the more severe variety. The character has to go to a special school for people with mental disorders and disabilities, so it has to be amsevere enough case to require that treatment.
Thanks for the help!
