I dont know if it will work, but keep yourself busy as much as you can. If you just sit around and think about it, well its gunna hurt you. So focus your mind on something else. Go out with your friends as much as you can, and check out every hot guy you see, then youll be like hmm this isnt so bad, cause if one of them talks to you, you wont have anything to feel guilty about cause your a free girl. Them things always helped me when I was going through hard times with my boyfriend...
But these ones helped me the most out of ...Anything!!!!
Listen to avril!! Go buy or download "let go" and "under my skin" those are the 2 most incredible cd's I have ever heard!! And im sure you can relate to the things she sings about!! If you dont have money or a cd burner, I will burn them for you and send them to you!! Thats how much faith I have.
And write. Get a book and write down all your feelings, and everything you have and think inside your head. Sit all alone in a quite place, and just write your heart out. And then a month later when you go and read it, youll say "omg, I was so stupid" (thats what I always did) and next time you go through a break up, youll remember how you felt, and you can deal with it better.
