Why am I not good enough?

Why 
              do I set myself up, just to get let back down?
              Why do I give it my all, when you can't even give it a chance?
Am
              I that blind? Blind enough to look past the flaws
              everyone else can clearly see, to just see perfection?
            Am
I Not
            as pretty as the other girls to you?
            am I really that bad? It's like I'm falling,
          yet no ones catching me. I just want everything to be
Good
          wonderful, perfect. People try to paint the perfect picture
          and they cry when no one is looking, but they don't notice
          their tears smudged the painting. I've had
enough
              heartache for the both of us.
            One day when I'm gone you'll realize what you had
              And could have kept. I just hope it's good enough for you
