I believe that humor is the most curing of all emotions, so if you have some time, here is a very funny video to cheer you! Do not stop to smile at a stranger, do not be afraid to say something nice, and never ever criticize unless it will really be thoughtfully and carefully explained to the person you are reviewing. Our lives are so busy, chaotic, and you all need to slow down and enjoy each moment as it comes along.
Let me know how you are doing, and what you hope to improve on in the next few weeks. I would love to help!
