The weather may be making you feel totally “blah,” at the moment, but just remind yourself that you have the power to change it. (Your feelings, not the weather, unfortunately.)
The good news is that you're resilient and you can adapt to change, and if you can't, the better news is that life is constantly changing.
You're having a blah day, not a blah life
Life is filled with moments, and you have to enjoy them all
