[Idiom] I am going bats. What does it mean?

[hoshi4]

Hello,

I am writing a BS thesis about idioms and I've come across the phrase: I've got to get out of here, I'm going bats. I feel panic.
I assume that it means I am going crazy or something similar, but I cannot find a definition of this phrase.
Can somebody help me to understand what it exactly means and whether it is really an idiom?
Thank you!

Welcome to the forum.

Yes, it means crazy or insane.

WordReference Random House Learner's Dictionary of American English © 2016
bats /bæts/
adj.

You'll also hear 'batty'.

You may also hear batsh*t crazy as a slangier form.

Also there is:

bats in the belfry

There is, though that can't follow "I'm going ...".

I'm going bats.
I'm going batty.
I've got bats in the belfry.
