I'm really sorry to hear that, Little. Look at it like this: It's out, nothing you can do to take it back. Im sure you're very embarrassed, but it's not the end of the world. It sounds like a very personal text, but was there anything truly embarrassing in it? If it was about what you want in a partner, that's the kind of thing you would post on an online dating website, so something.
Just think along those lines: Face reality and look at the positives (or at least put the negatives in perspective).
