I loved this story from Tara Brach in her book Radical Compassion:

I like to tell students the story of a man who went to a mindfulness retreat because his therapist said he’d feel better if he learned to meditate. The retreat turned out to be a real roller coaster. Yes, there were moments of calm, but he also plunged deeply into fear, anger, and grief. The next time he saw his therapist, he told him he’d suffered horribly. “How could you have promised I’d feel better?” Nodding sagely, the therapist replied, “You are feeling better . . . you’re feeling your fear better, feeling your anger better, feeling your grief better!

Let’s keep practicing, shall we?
