Trigger warning for eating disorders!

I've been talking with a dietitian about my eating disorder, Avoidant Restrictive Food Intake Disorder (ARFID), and she's been really encouraging and helpful. So far, I've really only been able to include red lentils and frozen spinach in soups and some other foods, but she told me that's really good progress since my diet is actually pretty broad for someone with ARFID.

I always thought I was just picky, but having confirmation that dry heaving, drooling, and vomiting after tasting food I can't eat is NOT NORMAL it made me feel a bit better that there's a reason for it. My husband and I talked about it the other day and he brought up how restricted our diet is and that most foods I eat are either mushy or orange (for various reasons, not specifically because I like to eat orange).

I've been thinking about it a lot lately, probably reading too much about it, and now I'm convinced my diet is the worst and I'm going to die a horrible death in my 40s due to my diet. I feel like I should just stop eating unless it's healthy, but then I would only eat lunch if I had leftovers and dinner if I made something from scratch, which I don't always have time for. 

Is healthy even a word anymore? Is it okay to eat only 5 healthy recipes on rotation every week? Am I stressing myself out for no reason and possibly making my ARFID worse? I'm just real upset about it all.
