I had an issue with my college library as well, though my situation was different. I am fine with the library itself, as well as the books inside of it. I went in there all of the time between classes to browse the web on my laptop, maybe get a little writing done and things like that to waste time. When the time came where I actually needed a resource from the library, I felt like I was facing a giant wall because the books were on the opposite side of the library. I wasn't comfortable with going to that side of the library at all. I felt like that if I went over there, I would have a panic attack. I talked to a few close friends about it and they didn't seem to really understand what I was going through and the distress the thought of going to an unfamiliar place like the opposite side of the library caused in me. However, they did keep encouraging me and pushing me. I talked to myself in the library everyday (of course not out loud...at least I think it wasn't) trying to will myself to go. It's either that, or I fail the paper. Luckily for me, eventually I managed the feel good enough to go over there. And I accomplished that. Although I still felt (and still feel) very uncomfortable while over there. I guess it's the way the shelves feel smothering and cluttered or because it's like a confusing maze. I'm not sure why it makes me feel uneasy, but it does.

Although my problem is different from the OP's considering what I was feeling was more anxiety rather than OCD (I do have some OCD I think too).

As for counselors, therapists and doctors and such...I would probably just keep my mouth shut. I know I need help sometimes because there are some things my friends can't really help me with, but I don't feel comfortable with going to a professional. (And there is also the costs to worry about). Anyway, I put in my story and 2 cents.
