I made my mother cry, does anyone know how to comfort her?

I am Non binary and I told my mother as such a few days ago. She did not take it well and the past days have been icy. We were in the car and she asked if I was mad at her. I told her yes, and explained that I felt disrespected and was angry at how she had responded. We argued for a bit but finally got to a place of understanding, and she asked me if there was anything else. I asked her to stop calling me her daughter and I think that was the last straw. She started to tear up but composed herself quickly. I gave her a hug but it doesn’t look like she feels any better.

I feel awful and want to comfort her. I wrote her a little love note and plan to make some little origami flowers and bake her favorite cookies. But I feel like I would be buying her off if I did that. Am I overthinking it or should I do something different? I hate that I hurt her, but what’s done is done, and I’m in disaster relief mode.

Any help appreciated <33
