The amount of sleep you get at night can determine the state of your mental health. If I get less than four hours sleep, I feel lazy ,depressed, and will have memory loss. I may get in the car to take the dog to the park, then find out I don’t have the keys and the dog.. I once started crying like a baby when I dropped a Big Mac between the car seat and the emergency brake. Feeling like a lazy bum always increases my appetite. One way to alleviate depression is to do what comes natural, take a nap.
