I hate saying I'm Sorry

I wouldn't wish this on anyone
Guilt over what can't be undone 
Guilty for something I cant control
I am being swallowed by its sinkhole
The pain completely all consuming
Raging so much inside it is fuming
I can't change what I did
Or the information that I hid
I couldn't do anything to save him
Couldn't bare to watch his light dim
I want him back more than ever
But physically we couldn't stay together
And I had to let his body go
Im sorry I didn't let you know
