1. Take a hot shower or bath
Wash the day off. This will relax you and make you feel refreshed and renewed.
2. Change your clothes
Take off what you wore all day and change into something different. Opt for something comfortable that makes you feel better. I'd probably go with a cozy sweater and pajama pants or yoga pants this time of year.
3. Drink something warm
Some hot tea or cocoa will comfort you, warm you up to make you all cozy, and feel like a bit of a treat after a hard day.
4. Watch or read something comforting
Choose something cathartic if you're in the mood to cry, or something you know will make you laugh and cheer you up. Above are some of my faves but I also love watching old episodes of shows I love, like Gilmore Girls or The Office. I know what's going to happen so there are no unpleasant surprises and there's something comforting about returning to characters you love...like old friends greeting you.
5. Go to bed
If you can do any or all of the above from the comfort of your bed, all the better. Get into some cozy jammies, bring your hot drink and your funny book/show/movie to bed. The sooner the day ends, the sooner a new one can begin and hopefully it will be a better one!
