This is not me

This is not me I feel inside,
at one point my soul must have died.
I held back info and sometimes lied,
I sat and laughed while a friend cried.

I've done and said things that were low,
the reason I changed, I may never know.

I know at one point I devastated my wife,
probably made her want to take her life.

Now that I've felt true pain inside,
I've sat, and thought, and realized.

I might have hurt them, but not as much as me.
Because I've lost my integrity.
