Can you offer some cheerful advice?

Ok I have had probably the worst couple of months of my life. The past week I cannot stop crying. So I would love it if you can link me some videos or even advice that always cheer you up during rough times in you life. I know this question gets asked a lot but I’ve looked at all the videos I could find on other threads. It can be music, cute doggies and kitties, advice, jokes, shows ect.
