Positrons are different from protons. Both have a positive charge, but a positron is an elementary particle of a similar mass as an electron. They are rather rare in nature which OP was noting. Protons are made of three elementary particles, much heavier than positrons, and are, I imagine, present in nature in about the same order of magnitude as electrons.

Whew. Good. I thought it was just me.

I wish I had a friend who could just be there while I tried to get it set up. Honestly, I’d peroxide pizza, beer, and video games just so I don’t collapse in a mess of confusion and self doubt when something goes wrong. I don’t mind doing the work, but I don’t know if I have the patience to figure it all out.
