Sustained compassion is compassion for people who aren't going away any time soon, like our family members. One example is BALM, a recovery program for family members of recovering addicts.  We're going to 28,686 days on average - which means self compassion is in order for when it goes well and when it doesn't. To sustain compassion we need to look at both the short run and the long run. To sustain compassion over the long run, we have to include ourselves in the circle of compassion. Two skills that help are checking in with ourselves and checking in with the situation before we decide what a wise compassionate response would be. As we check in, we can adjust how we respond to people and change up our interactions with our family members.
