GF left me and I'm not sure what to do?

It's tough when someone you love dumps you, sorry to hear that! You sound like a great boyfriend! You should really give her a few days. Maybe it is just because of college and tell her that you can write, text, and/or email each other every day (when she goes to college)! Never give up. You should really step outside take a breather and actually eat. Tell her your feeling deep down inside you have for her and really try to talk to her about it. I really hope I help.. And maybe if there is a relationship guidance councilor near-by you should really go there. And tell her how much you care about her.
