This is not an easy time for you, but some personalities on these boards will be straight forward with recommendations and sometimes come off as crude, just be aware.
In regards to your latest post, brush it off brother. Do not carry the weight of stress and failures into the next day, it will never help you out.
What I think you should consider in the future (future being a month or so from now) if she brings up relationship, just listen and don't "push" her. "Pushing" is when you confine her to embrace the love you have for her or reject it. The "I Love You" (ILY) comment only gives her 2 options and she is in full, and complete, rejection mode right now.
Another "push" that you need to stay away from is being a open doormat. She already knows you care, so now go out and have fun. Don't just sit around and be mopy and depressed because that did not attract her when you 2 first met.
This will be a long road, nothing on Earth is going to remove the pain overnight. Develop healthy habits and start to learn more about yourself and the things you enjoy. You can only affect your actions and your level of happiness right now, so just focus on those.
"Don't chase people. Be yourself, do your own thing, and work hard. The right people - the ones who really belong in your life - will come to you. And stay." ~ Will Smith
