I know burnout is real and sleep is important, but showing up for your friends and nurturing the relationships by taking them up on their kindness is real too. Go on that long drive to make it to your friend’s goodbye party, you could make new relationships there. Make a real plan to visit them in their new home. Or see your friend at work when they said they’ll give you free appetizers and tell them all the hot gossip. See their show. The culture in the US at least, makes it really hard to maintain friendships as you get older so when someone provides you a clear way of strengthening that bond, reconsider it. Caveat of course is level of friendship and if that kind of attention is wanted and also sometime you do really need to shut down for a bit … but make it up to them after, bake something or visit them later, etc.
