If you got diagnosed as a minor, how?

I am a teen with (self diagnosed) ARFID. I know many people look down on that and that is why I want a diagnosis, but I also want it to bring awareness to my parents, so that they understand how I feel. If need be, I could just wait until I'm an adult and go get diagnosed myself, but I'm just curious on how people got their diagnosis at my age. I expect the most common answer to be, "my parents got concerned and took me to a ___", but I'm still curious to hear any of your possible stories.
