I'm extremely hard on myself and it usually comes out in self destructive behavior. I notice on the days when I'm struggling the hardest to be nice to myself are the days I need to get out of my head and go outside for at least a 15 min walk. A fun phone call to a friend, and maybe I just need to get up from my desk and stretch. Whatever it is, I'm trying to be compassionate to myself rather than tell myself what a loser I am (not even kidding) I think the more we treat ourselves with compassion the better we feel about extending it to others. Forgiveness comes easier too. Telling myself it's okay, that today sucked and you didn't get everything done off that check list but tomorrow... tomorrow you're going to kick ass.
