Looking for treatment/Finally talked to my mom about getting help

Probably my biggest win! My parents have always known I am a picky eater, but it has gotten way worse since going away to college. I had a big health scare last week from eating so little, which pushed me to start looking into treatment options.

I'm 99% sure my specific eating habits/anxiety are from ARFID and not a different ED, so do you all have any advice on what to do next? I have an appt with my PCP next week for some bloodwork. What does treatment look like, and are there any good online services (I live in a rural area)?
