i have been wondering about this connection for a few years ever since observing traits of OCD within myself. i have very strong urges and compulsions to do certain things very often, which in some cases feels like addictions to these things, like checking various things on the internet and cracking my knuckles repeatedly throughout the day. i cannot focus on one thing hard enough to stop myself from doing these things, especially when doing something like homework. i will check facebook and ebay so many times during a night. i have an issue with buying things online (my video game, record, and book collections are so sweet right now) every since i was a kid i had strong compulsions to do things like roll my eyes, crack my knuckles, count my steps, make noises with my throat and so on. i have to do these things or i get very frustrated, so i do these things to release. i feel like forces out my words when i am blocking is similar to these urges. i know i shouldnt, i know i should stop, take a breath or two and try again, but the urge is so strong that i cant fight it.
