Your T just can't seem to stop triggering your younger parts can she?! What did your T say/do that upset your 13 year old?

How long have you been with your T now?

Have you asked your 12/13 year old why she likes to swear so much? She might just be rebelling even against you a bit - because she knows it makes you uncomfortable, but I'm glad she stopped before going too far with it.

I'm not sure what to suggest to help you feel more safe, outside of learning how to handle situations in a way that would be satisfactory to all of you?

Have you had a talk with your parts about what's acceptable and what's not? I'm just trying to help brainstorm.. hmm.
