Any Suggestions, I can't think of names anymore

Why are you beside me
Why do you care
I always screw things up
How can you put up with me
Forever worried
Worried about when you wake up tomorrow will I still be there
How can you smile
How can you say I love you no matter how much I hurt you
I see the pain I put you through
How can you stay so positive
I know I love you
But I seem to hurt the ones I love so much
How can you put up with me
Putting myself down
Why do you look at me in that same way
I'm a freak
I'm a phsyco
I cut away my pain
I've hurt you so much
You don't know how much I wish I could tell you that it's no more
I couldn't promise anyone that
I always screw up
Just wanted to say I'm sorry
I do love you
No matter what I do nothing will change that
