. . .

I never knew how much I'd hurt myself until it happend. They told me it would happen and yet, I didn't believe them. I told them I'd be fine. I told them I'd prove you wrong. But I was wrong. I hurt myself, I hurt everyone around me and I made them hurt me

I thought I might redeem myself and fix my mistake, but once again, I was wrong. They hated me more and I was left alone. I thought I should hide away and believe that no one would notice me

Then he came. He made me smile when no one else would. He made me think that I would never be alone. He held me close when everyone pushed me away. He made me a better person. 

Who am I?
