No, I'm not the slightest bit weird. [Heh, you asked in the title.]
Were it me, I'd start with the insurance company. Make certain the provider didn't foul up in their claim filing. That alone accounts for probably 25% of medical collections--at least. I got a paycheck I'll bet on it if the data were available to reconcile the wager.
My mantra is NEVER pay a collection or charge off outside of a PFD unless you HAVE to pay it. Opinions vary, but you have options you can pursue BEFORE you pay it. Once it's paid, you have zero leverage.
I totally get your apprehension. The collections are there, and they ain't goin' nowhere. I got laid off twice about 7 years ago, and I'm still paying for the subsequent credit damage done. Layoffs hit ya like that, and keeping that safety net helps to mitigate future woes.
The bad credit I already have don't scare me all that much. Not much I can do about it, and not much it can do to me--for much longer.
The bad credit I don't have and could acquire in the future scares me plenty.
