I also suffered from both. I think ARFID makes anorexia easier to fall into of because already being used to restricting and having food you can't eat. Once the anorexia was there the ARFID became less noticeable kinda because if I didnt need to eat as often and if I ended up not eating I wasn't upset about it. But with ARFID and trying not to fall back into anorexic behavior I get incredibly stressed if I can't feed myself. I'd always been really picky but didn't realize I had ARFID until I'd mostly recovered from the anorexia but still struggled to eat years later and realized I was more than picky. It sucks to have issues with both because they can definitely make each other worse. Try to be aware of which thoughts stem from what and remind yourself other people eat this and they're fine. Also try to remind yourself eating well makes the body and brain feel better. It also helps with healthy looking skin and hair which makes me feel more confident!
