...to pay for sessions to deal with a rupture a T created!

I had two sessions with L today. After the first one, we determined I could use more support. She offered a second sessions today or tomorrow. I agreed and asked for one today. Long story short, she triggered me badly and instead of dealing with the other issues I'm struggling with, we had to do a session to calm the rupture. "Calm" not resolve.

I told her it's not fair that I'm paying for this financially and emotionally and it doesn't affect her.

I don't know what to do. She wants me to write to her about my anger. It's hard enough feeling anger especially towards her, but to also express it to her.

I hate ruptures...
