I’m really taking this to heart.
Look at the magnitude of the problem I’m trying to “fix.” Justifiable grieving and a lifelong depression? You cannot fix this. However much of yourself you pour into it will never, ever be enough. There is in fact very, very little that I control in this world beyond the reach of my little fingers. You can only make the best of whatever is within that tiny little reach.
So, what am I willing to do? Decide what I can and am willing to do for this person. Do it, and make peace with it.
