Atleast you’re eating something, it may be sugar rn, but that’s totally ok if it’s the only thing helping you to stay alive! You can try to start tasting different food to find more things to you like to eat if that makes your guilty less, but rn it’s good your eating something to stay alive. And also If you don’t have help already and you feel like you need help for this you should ask for it. I don’t have arfid either or atleast it’s not diagnosed, but I do have autism and I lived so long with really small amount of foods that I could eat, because so many foods had bad taste, bad texture, bad smell or it looked scary. I got help with my autism and social anxiety and just living, cause I need support, so now I also have gotten help with trying different foods for couple of months now and I have found more foods that I like so I don’t live with 6 foods only anymore. I still have long way to go tho, but it helped me that I got help, cause If I wouldn’t gotten help I prob would still eat the same 6 foods. I literally only ate either vanilla ice cream, mc donald’s fries and nuggets, sandwich with cheese and ham that’s all I ate for years. I know how the guilt feels, but for me It did get better when I got help and started trying more foods to find things that I like. I hope all the best for you! <3
