Can someone please give me a non-political description of learned helplessness?

I want to know if learned helplessness is a real thing. I was reading the Wikipedia article about it, and the part where it says
"
Over the past few decades, neuroscience has
shown that the original theory actually had it backwards: the brain's default state is to assume that control is not present, and the presence of "helpfulness" is what is actually learned.
"
struck me as strange, and possibly political.
It reminded me that the new professional psychiatric consensus regarding gayness is that it's not a mental illness, and that people are born gay. The change in consensus in the case of gayness is obviously political.
The foundational theory said the opposite, and gayness used to be listed in the DSM as a mental illness.

Personally, I want to know if I am suffering from leaned helplessness to a degree. If it is a real thing, then maybe knowing more about it would help me escape it.
Ideally, I would like to be able to somehow permanently get rid of it, or construct some sort of sheild against it that is independent of my own brain.
It seems that whenever I have escaped it or am close to escaping, I somehow slip back down again. It would be irrational to assume that it always has to be part of my life, right?

Sorry for the blog post.
