When you don't meet your own expectations.
So I did a thing and everyone who experienced the thing enjoyed it and wanted more. Normally, I would be over the moon.
And yet, I thought the thing I did was just okay. I was really disappointed because I put a ton of work in and it wasn't as good as I know it could have been.
And yet, it is super hard to share that disappointment with people who are happy with what you were doing.
