Wow, Teal, I think something amazing happened to you during your session. I remember the first time I felt anger toward my T. I look back on it, and it was actually a step of progress for me. In my life, I had never recognized anger for what it was. I usually denied it, or unintentionally called it something else. Growing up I was not allowed to express anger.
Hugs to you. It may take a few days to process that session. If you are still in confusion, perhaps you and your T. can discuss the same things again. Proud of you.
