Bubbles are always cheery, even when you have to stand in temperatures below zero to blow them.  If you live in a cold part of the world I encourage you to give frozen bubbles a try today.  It has to be quite cold.  I find about -10C and below works best.  It also needs to be still.  Wind is the enemy!  I use a solution of water, glycerin or corn syrup, a tsp. of sugar and water.  The glycerin makes the bubbles stronger and the sugar will make crystal patterns as the bubbles freeze.   I put my bubble mixture outside for a few minutes before I head out so that it gets cold.  I use the snow on my deck railing as my base.    I use a straw to blow the bubbles and I blow them gently onto the snow base and hope they don't pop too soon.  

You need patience to get to the point where the bubble will remain in tact and crystalize enough for you to be able to photograph it.  It can be frustrating but the results are definitely worth it.  If frozen bubbles are just not possible for you today, show us what else makes you cheery.  Like this bubble, try to use the rule of thirds when composing your photo today.
