okay..is this OCD.

sometimes if i'm talking to someone, or i hear someone talking, on tv
or anything like that. and a sentence sticks out to me. i count it out
on my fingers until the words fit perfectly on ten fingers. if that
makes anysense. ill go backwards or anything. and if i can't do it, or
it takes me a while, i get really anxious and breath faster and faster
until i can succeed.

OCD?
or me being crazy?
