Co-sign on everything that has been said so far. Especially, the sleep-aids and no contact. Emotional heartbreak is a killer! But just remember that you, although sometimes it may not seem like it, are stronger than this. You can overcome this, and move on. And as my best friend says, "this relationship taught you a lot about you as a person and what you want in a guy. be thankful that you know this and can move on to someone more compatible(sp?) now" It may hurt to read the move on part.... but I promise it will be okay.
Plus, I'm in Lexington - so give me a "holler" and we live it up at Two Keys.
That will make you feel better, Two Keys men....lol
