<p>Precalc in senior year isn’t behind in math; it just isn’t ahead in math. It’s possible that, given the right teacher, etc., you could become good at math. You may never win a Nobel prize in math, but there are thousands of mathy jobs that need to be done, and you could probably do most of them. Conveniently, what you like coincides with what might put you in an easier-to-find-work career field. I’d recommend a school with both, and try to find math-and-science things you can love and be good at.
There are hundreds of very good schools in the US. It is not necessary for your neighbor to have heard of a school to make it worth going to. Maybe you’ll find a school that is a good fit for you and will show you how you fit with math.</p>
