I'm used to battling through 'sadness' on a daily basis, so I don't know how I'd describe that....suck it up? haha
If I'm sadder or more depressed or melancholy than usual I'll usually grab an animal to destress and get myself back on track. Alone with my own thoughts isn't good and I don't want to subject a foul mood onto my kids, so I try to keep everything moving forward without leaning on any person.
A bad or grumpy mood is extremely rare for me and is usually the result of a direct problem that I deal with in that moment to fix, thereby alleviating any reason to be upset.
