She cheated on me, its really getting to me. I've never been this way before please help.?

Shahin, here's the thing that you need to understand that will help you get over this girl. Happiness comes from the inside. See, this girl wasn't REALLY making you happy. You were just projecting that onto her. But don't beat yourself up over it. All of us have done it at one time or another in our lives. See, no matter how cute, fun, smart or whatever this girl is, at the end of the day she is still JUST ANOTHER GIRL. Even if you two were to still be together, there would come a time when things got absolutely stale, boring and routine. It happens with everything just like getting new clothing, cars or whatever else. You simply need to realize that you live in abundance. There are literally millions upon millions of women out there who would love to get to know and spend time with you RIGHT NOW!!! Seriously, I know it's hard, but just move on. You are only holding on to an idea you have in your head about this girl. She could never make you happy. No one can. Once you understand this with your heart, you can live life all out knowing that people can only share themselves with you, but not complete you. You are already complete. Good luck buddy!
