There are new-fangled jobs such as "Death Doula."

Then you have mortuary science. It was a degree program where I studied. (On graduation day, my college cohort was seated right in front of them; they seemed like a really fun bunch of folks.) Mortuary Science is a great "undertaking" if you like "working with people." LOL

But seriously, I would think medical research would be something to focus on. A Technician of Biotechnology (if there is such a thing) might be a quick certificate program and could get you into a place that might pay for a college degree.

I didn't want to discourage you, and I love math a great deal, but I can't image it can do anything for you, unless you pair it with Computer Science or Business.
