Thank you, tulips30. I don't like confrontation much myself, but now that I'm learning these DBT skills I feel like I have a chance of getting through one, like I did last week. I appreciate the pat on the back. The therapists each gave me a hug when it was over. That really helped too. Group was very supportive, more than I imagined it would be.
Interesting thing about perceptions: I was sure everyone in the DBT group was friends with this lady and they'd all get mad at me for stirring up the pot. Turns out they were having similar issues with her and they weren't friends with her at all.
My therapist tells me that I need to come up with different interpretations for thoughts like that and she's right. I almost didn't confront this person because I believed that they were all friends. Even though it was very scary for me, I'm glad I did it.
Now I just have to get through group Thursday night without freaking myself out thinking that she's going to show up.
