For me, having a job to go to was a life saver, mentally. I worked 4 mornings a week at a small company. Sewing department was just 6 ladies. My boss knew a little of my loss and cut me spme slack on "bad days" because I was a good worker, willing to do the more irksome sewing tasks with a smile most days. If I told her it was a bad day, I would get a job that day that was easy and repetitive.
Leave time and space for yourself on bad days. On good days, attack all your favorite projects with all the joy you can muster.
