O.C.Distic - A person who can't think straight because their brain is too

A person who can't think straight because their brain is too obsessed with tiny things and they can't focus on anything else.

I had to count my steps 7 times before I could walk to the store.

I had to line up my cereal boxes by color before I could eat.

I couldn't text my mom because I was too busy checking if my socks were matched.
