ARFID - just diagnosed

I had a virtual appt with my psychiatrist and discussed the possibility that I have a eating disorder called ARFID. He had me answer some questions and then sent me a test to fill out and send back to him. I received a call from him confirming my diagnosis and he told me he would see me back next week to discuss treatment. I’ve been googling like crazy and I can’t find any definitive answers about how this disorder is treated. I am a very selective eater and have become extremely uninterested in most food. I tend to eat the same things over & over again & often struggle to eat enough calories. Does anyone have any experience with this?
