What am I to you?

You've got me like a puppet on your strings from the very beginning. The four years of friendship we had means close to nothing today, that entire period of time, I have been completely oblivious to every hope and every ounce of happiness you've left me hanging upon. In the end, they mean nothing. And it hurts, merely, to know that you've only been using me for your own benefits. Coming to me, when the rest of your world has excluded you, then forgetting me for the time being while you're back up on your feet. That isn't even considered a friendship. It makes me sick to the gut to even think of the pain you're about to or have already bestowed upon me, that huge amount of relation between us, has amounted to nothing. I could say the worst things about you and exaggerate how self centered you are, how shallow you act and how inconsiderate you are of the people around you, but I won't. I will walk away from you one day, and give you the good old finger.
