I don't know

I don't know why my heart I lend
I don't know why I pretend
I don't know why life has been a blur
I don't know why I'm never sure

I don't know how I end up doing stuff that I shouldn't
I don't know how i tried when I said I wouldn't
I don't know how you slipped away
I don't know how iam with out you today

I don't know when the days begin or end
I don't know when the wounds will mend
I don't know when life will continue
I don't know when I became nothing to you

I don't know why I'm so lost and confused
I don't know why I feel so used...
