Logans admission

Logan found himself to be fairly normal with a few odd quirks.
-the number five was his favourite; he counted his steps to five, cracked his fingers to five, clicked his pen in fives and if things weren't divisible by five they had a tendency to throw him off to say the least, bring upon an overwhelming feeling of dread
-organization; if things weren't where they belonged Logan would have a breakdown and need to fix it, if he didn't he would die
-cleanliness; Logan was paranoid he could get sick if he touched the wrong thing so he avoided touching anything.

More specific activities and routines went with this all such as scratching and light switches but otherwise a perfectly normal teen. That is until the fall formal. It was his senior year, he had almost finished with this and he was walking through the halls, one two three four five, one two three four five, one two three four five, one two three four five, one two three four five.
When suddenly he felt his body hit the lockers with a thud, panic in Logan's eyes, he quickly ran to the bathroom, great now his schedule was fucked up and he had to wash his arm. Just great. So perfect. He scrubbed at his hands first, then his upper arm but then he noticed the bruise wasn't even. It took an hour of scrubbing for anyone to come in, it was a teacher, shocked at a disturbed Logan with bleeding hands and arm from the intense scrubbing. He went to the nurse and sooner or later his parents were called. 
A month later he went to a psychiatrist, getting diagnosed with OCD. He was put on meds but the constant breakdowns and accidental self injury lead to hospitalization.
Logan took his bags, tapping his knee as the paperwork was filled, trying not to freak out again as he had when he was at home after he had been told he would be admitted.
Logan soon set up his room, not having a roommate but having a big window. He soon realized he didn't have a curtain, panicking.  Great now he would probably be watched while he slept and be killed.  He put some of his books down, twice, no that wasn't right, he did it again...  three more times. There five, perfect.
He did things along the lines of that until it was all perfect. But it wasn't right yet. He couldn't take it anymore.
Soon he was called to group, Logan raising his hand in group to talk. He got odd looks that night
