I don't think worrying about a friend is something worth calling yourself an idiot over.

[he chides without mincing his words, giving a tiny shrug as he does so]

And I know it might not feel like it's "enough."

[it hurts to watch someone you care about suffer, knowing that there's very little you can do to alleviate the pain]

But I bet your friend appreciates it way more than you think he does.
