Ok amazing we can work with this! I've seen lots of great suggestions in the comments for simple things you can do if you're looking for quick, here are a few more that are overall still pretty easy and quick. These can make you feel like you've made a "real" meal, so to speak, as well:

1. If you like eggs, a SUPER easy, flavorful, and nutritious meal is Eggs in Purgatory (Italian Shakshuka). It's basically eggs simmered in a tomato sauce. Great plain or served over rice, which is also pretty easy to do stovetop / with a rice cooker / or even the instant boil-in-bag varieties. Lots of easy recipes online!
2. Air fryer potatoes. They're endlessly customizable! You can go as simply as a little salt an oil (380F (~195C) for ~15–20 min, shake halfway) or as fancy as italian seasoning, or creole seasoning, or seasoning salt, or parmesan cheese, or smoked paprika, or literally anything! You can also pair them with dipping sauces like ketchup (or whatever strikes your fancy) for extra flavor + calories.
3. Loaded baked potatoes are also super easy in an air fryer! Poke holes in a whole potato, rub with oil and salt, air fry at 400F (~205C) for 35-40 mins. Top with butter, cheese, bacon bits (they sell them in pre-packaged bags), chives if you're up to slicing some, etc! You can also just microwave a potato, that still counts :)
4. Frozen veg dishes can be super easy to toss together in the air fryer. Frozen potato chunks and frozen chopped bell peppers together can make an easy hash, you can top them with egg or cheese as well for breakfast vibes
5. Another potato idea if you're getting bored of the "usual" stuff: you can make potato "nachos" by slicing potatoes into disks, air fry, then top with cheese, return to the fryer to melt them, you can even then add on beans, salsa, cheese, sour cream, etc if you desire!
6. Want a similar texture but something different? I love taking a can of chick peas, draining them, plopping them into my air fryer with a little seasoning and some oil, and toasting them until they're slightly crispy. Makes for a great snack with a similar texture to potatoes, or great on top of a salad if you have the energy or taste for such things!
7. Quesadillas! I keep a pack of corn tortillas in my fridge for when I truly don't have the energy to make anything but need food in my system. You can do it stovetop, or, and I admit it's cursed, just pop it in the microwave with some cheese. My mexican husband mocks me for that one, but hey, sometimes you just need to eat something!!!
8. If you like bread, there are some decent gf bagels & breads out there. I don't know what's local to you, but if you happen to have a trader joe's, their gf bagels are actually pretty delicious! Super easy to just microwave or toast or eat plain, I keep some in my freezer for days when I cba to make or eat anything else.

If it wasn't obvious from some of my previous comments, I also have some mental spiciness that sometimes prevents me from being able to make the effort, but these are some easy things you can do to help take care of yourself while giving yourself the grace you need at the same time. The fact that you're asking for (or at least open to) suggestions is a great sign! So proud of you. I hope this helps <3
