I have a "plan" I use on myself when I get too anything; depressed, anxious, whatever. When things seem to be the worse they can be, I figure it doesn't hurt to do things I don't want to do. How about cleaning the bathroom? LOL, things
could be worse. Usually I think of something to do that's more "enjoyable" than cleaning the bathroom or cleaning out my closet or whatever it is that I've been avoiding. And, once I get started working on something, I get distracted from my worries or bad feelings and shift gears because we can only "focus" on one thing at once.
So, I would suggest making a mental list of things you don't want to do and when you come in and are standing in the kitchen ready to give up, say to yourself, "Well, I might as well ________." I call mine my "Rutabaga" Plan because the name, "rutabaga" always makes me smile/laugh, I find it such a ridiculous word. Now all I have to do is think "rutabaga" and I cheer up or look for something to help me not be as anxious. With your guilt, I'd ask myself "Is there anything I can do about it right this second?" and, of course, the answer is "No" so I'd just move on to something else. I love this (down below the advertisement, second half of the screen) about "Beating a Dead Horse":
