Is there a name for the feeling "Damn, I already asked this question three years ago"? [closed]

I'll copy from Meta:

I admit I'm sometimes too quick with the gun when firing away questions.

Does the feeling "Damn, I just asked this now, and I see it's a dup of a question I asked three years ago" have a name?

Preemptive word for the smart: "Lazy" is a good term for the asker, but not for the feeling.

I offer the term déjà vu. Though not literally true, it captures the spirit.

Perhaps chagrin is the word you are looking for.

chagrin \shuh-GRIN\, noun: 1. Acute vexation, annoyance, or embarrassment, arising from disappointment or failure.

You could use something as simple as- memory lapse!

Or probably the sentiment could be described as feeling sheepish, discomfiture, vexation, chagrin.

If you want to put it light-heartedly, you could say, you are mortified at your temporary amnesia.
