what am I?

Dear Readers,

I am very useful, I guess I can say. People use me everyday. I am very still, however I can be very comfortable. Everyone loves to pour their feelings into me and I often get marked. I get sticky all the time and it does not feel good. I wish people would take some consideration but they usually do when they get in trouble. I am hated by many kids in the world and only a few appreciate me. I am alone and I can’t stand it. I feel like I die a little more everyday. I hate this feeling but that just comes apart of the package. This is me and I have the rest of my life. There is nothing I can do to help myself other to ask for your assistance.

Signed,
My Hurt Self
