In a dilemma

So for the past month I've been struggling with a bum foot. I moved it the wrong way and got a sharp pain, so had been nursing it. Finally thought I could get back to my daily walks then last week I did a face plant with the sidewalk. All scrapped up and hurt, bruised and stitches. Now healing but my knee is messed up. doctor says blood in the knee. Warm packs. Not good. Needless to say no exercising for a while. Some of my weight loss is coming back 😔. I am having comfort food cravings that are hard to resist
