Don'T You Understand?

My blood flows like water in a stream. Filling this sink. This sweet sting; an addiction I can never seem to escape. I'm dizzy, just like always. An effect I shall never outgrow. This is my heroin. Don't you understand? Wait, I keep forgetting. You don't, and you never will. Concerned by scars, sometimes you annoy me. But I've come to care less. Your just like the rest. "I just want to help" you say; as your face grows to a look of dismay. Sometimes it makes me laugh inside, the fact that you lie so well. You and I both know that everytime you say that, it's never going to change me. Yet you are so persistant. Are you jealous? Jealous that something is actually making me happy? I've learned not to argue. Just to sit and listen to you blather on. I know every line, as if rehearsed in a play. These things I've heard so many. You will never understand how this makes me feel.
