hmm i also dont think this is ocd, but i can relate to you totaly. ive been going out with my bf for 3 and a half years now, and because im only 17, i cant yet move in with him. because of my home life, and my depression, moving in with him is pretty much the only thing im looking forward to in life, so im ending up thinking about it all the time, and feeling bad because i know it will be atleast 2 years before im done with education and have worked enough to raise my part of the money we would need to move out. im afraid as im kind of in the same boat i have no advice i can offer! sorry about that. but just so you know your not alone in this feeling, i thought id post
take care and i hope it all works out for you!
