What I would like to propose is: give your body and soul what it needs/craves. Try and make healthier choices if you decide a meal or snack is in your best interest. And then, let it go, move on. Keep going. Do a bit more, eat a bit healthier, sleep a bit more, play a lot more, and listen to what your soul and body tell you.
What I am learning in my recovery from depression and anxiety is that my feelings are never the complete answer. And often, my feelings just are. If I can separate from them just a bit I can see myself as safe and healthy, even as my bear-feelings are shrieking, "Holy crap, you know what happens when things start feeling this good!"
