Hello Lorii: Thanks for sharing your experiences regarding your daughter's eating disorder.

I see this is your first post here on PC. So... welcome to PsychCentral!

I hope you find PC to be of benefit.
I myself am not familiar with ARFID. But that's not surprising since I don't really know that much about psychology in general or eating disorders in particular. Hopefully though there will be other members, here on PC, who will have some experiences with this condition they can share.
Here's a link to a YouTube video by family therapist Kati Morton on the subject of ARFID
Since you mentioned the problems you've had with your husband's views on mental illness one additional forum, here on PC, that may be of interest to you would be the relationships & communication forum. Here's a link:

My best wishes to you & your family...
