Hi, Smilin.
I'm sorry for your loss.
You said "binge" and you also said "two chocolate cupcakes." That was it??

Or have you continued to eat sugar and flour? You also said, "diet Pepsi." I have to say that none of that sounds like a binge to me. Just a slip/small cheat/whatever.
You asked about gentle foods--that is so different for everyone. Maybe clear chicken broth with some chopped up chicken and little shredded veggie of some kind? For some people, dairy is gentle; for others not. If yes, why don't you try a little full-fat, live culture yogurt? Stoneyfield, I think, is a full-fat brand. There is a thread on here somewhere about the fact that the live culture basically "eats up" the carbs in the milk, making it a good food--in moderation--for a low-carb diet.
Are you attracted to hot or cold foods right now? Sweet taste? Sour taste? Salty taste? Smooth or crunchy texture? Spicy or bland? Thinking about these attributes can help you name a food that you might want to eat.
Also, if you can't think of a paticular food, but you can tell us that you want something warm and spicy and creamy, for example, we can probably help a lot more. For that paticular combo, I'd suggest adding a little bit of heavy cream, grated ginger root, and a pinch of cayenne to the chicken broth I mentioned above. For cold/crunchy/bland, I'd recommend cucumbers, sliced into long spears and eaten slowly, with much crunching! Or diced and mixed with a little plain yogurt. Or sliced thick and spread with butter and salt, or cream cheese.
So, you get the idea.
I support you in your decisoin to record your food every day. Have you stared a journal here? That is SO helpful for me. And it makes it much easier for others to help you.
You said that you don't feel like cooking. Can your budget handle several meals out? Go to a favorite restaurant and be pampered. Ask for what you want. "Could I please have a little dish of melted buter" is one of my favorite requests. And, "Veggies steamed with no seasoning, please." Then, of course, I dip the veggies in the butter. YUM. Take a friend with you, or go alone.
Get a massage. Get a facial. Eat 20 perfect raspberries with whipped heavy cream and splenda. Eat 2 perfect spears of asparagus with hollandaise. Eat one perfect poached egg on a tiny bed of sauteed spinach.
Hang in there, and let us know how you are doing.
