I tend to excel at failing

As a parent, I've done all that I could with the thing's life has given me.

Still, my son is dead, and my daughter is so depressed that she's contemplated suicide.

Here I am, telling her how much I love her and how I'll always be here for her no matter what.
Letting her know that life is weird sometimes and it's often hard and unfair.
Insisting that there are good days ahead for her and her children.
Taking on anything I can to lessen her burdens.

But still failing miserably as a father.....

I'm not sure where or how it all went so sideways..?

I suck.
