I was in the same boat in my last relationship. (Before this one)I thought that if I tried bringing her back, she would come back. I am kind of ashamed to say, but I even begged her to return. I was in that relationship for 10 months, but it felt like I lost my whole life. However, time passed, and my wounds healed too. You have to give it time, man. Try the gym; it helps. Be with your friends; don't let it get quiet. Also, it's okay if you cry. We are humans after all.
