Some days I wake up feeling flat, heavy or a bit sad, and when I look for a reason, I can't find one. Nothing has gone wrong. It's almost harder than having an obvious cause, because I don't know what to fix. I've found that a short walk and avoiding my phone for the first hour helps a little, but I'd love to know what works for others. What do you do on low days that don't seem to have a reason? Do you push through, slow down, talk to someone? What small things help?
