yeah man you need to just move on - gather up your friends and go out some places bowling, cinema etc have a laugh put some fun back in your life.

I know it hurts when some one you feel so strongly for just goes out of your life. It hurts real bad and makes you feel like you have nothing, but you do, all you have to do is reach inside you and find it.

on the subject of changing so she likes u again - this is a no way simply because she should love you for who you really are, and not for who she wants you to be.

i think thats all -
Remember you just need to pick yourself back up and in no time at all you will have yourself a new g/f.
