Hey, Brook' ... Why do you feel you need to tell your boyfriend anything at all? I think there's loads of good advice above my reply, but here's how I consider these things in all circumstances: would I tell so & so that I have a heart condition? (ps, i don't) I'm way open with my depression when it feels right to me & makes sense, but otherwise, I don't tell, no more than I would tell about any of my other medical conditions.

Look @ it this way: if you tell him & he's cool, you just might have a keeper. If he freaks ... well, maybe you might be the one who should put on your running shoes. If a person can't love me bcz of my med conditions, well, shucks.

Good luck!
