I Have A Block Button On My Heart

Invisible Walls... A barrier that is just strong enough to hold any outside assailment. A fortress to keep every important pieces of emotions in place and not shattered when aggression happens. A jail to keep anyone from getting in or out, caging memories inside like it's not supposed to be remembered. A blockage, keeping pain from resurfacing. An invisible walls, to make you think you can see what's inside, but still, you can't understand what it is, let alone having it.
A fragile heart is trapped by its own decision.
Afraid that the past will repeat itself. Afraid to be hurt again, vulnerability creeping along. Afraid to show any kind, even a nuance, of emotion. Afraid to open up, just to be slammed close again. Afraid to be dependent. Afraid that in the end it's not worth the pain. Afraid to feel.
A frightened heart would only make a half person. Cold, heartless and emotionless, is enough to at least be half alive.
I am almost alive, and I don't mind.
