So. It goes like this for me:
Me: "I don't even know what I'm doing here/I don't want to keep disappointing you/I'd rather be anywhere but here (today)/I keep screwing up."
T: "All you have to do is keep showing up. That's what you can control. Don't try to control therapy or me or what you think I'm thinking. Just show up."
So, that's what you can do, too, right? Show up. Do what you can. This time, next time, time after time. Just show up.
