First of all, never think you're wasting anyone's time by expressing your pains or feelings. You'd be surprised how many people in our little community here care for you. So by all means, bring up any issue you have! There's always a free ear here to listen
There's definitely some therapeutic releif when expressing pain. I know the same stuff you're going through right now with this girl you care for. It sucks. Sucks somethin' fierce. Hurts to think sometimes, as you've expressed feeling when trying to go to sleep, or waking in the morning. There's not much I can offer for relief though. But I did want to say that I know what you're going through. Going through it right now. And sometimes knowing someone else feels like crap as well is a little comforting. It always works out though, it always works out. God's finger pushing you in the back toward some unseen result of this problem.
