That's horrible, cusack. But you did find an activity, and that's good! Think of it this way, maybe: every time you start something, she makes you regret it. How about this time, say, "I'll show her, I'll keep going to this activity, no matter what she says, and she'll see how I'm enjoying myself." I know that's much easier said than done, but it looks like she hasn't actually prevented you from going, just made you feel bad. And that's a step. Try to keep going. The more you think about it, the worse you'll feel, but if you go there, at least you'll be happy while you're there.
