I know how you feel, I often want to comfort eat out of stress, boredom or loneliness. It can be tough to stay motivated when those patches hit. But you already made the choice that you weren't going to do that and took your dog on a walk instead, so good job! This journey is more than about staying motivated, it's about choices. You can get through this shift, and you will leave feeling proud and accomplished that you did not resort to comfort eating to deal with it. You can do it.
Maybe instead you can look forward to a nice, long hot bath once you're done.
