I bet there’s something you’re good at, or even just okay at, that you might be good at teaching to someone who isn’t good at it.

I have periods when I go into a slump and I feel like how you described. I’m definitely not a role model, my life is falling to bits, and I’m a failure at life, as a certain family member likes to keep reminding me. But the fact that my nephew comes to me when he’s got a problem shows I do have something to offer. I bet there’s something you can offer someone, even if you might not have the mental energy right now.
