Wow, that was incredibly brave! Good for you for addressing this with your mother!!

I wish your mother would have responded with more empathy. It seems she may have become defensive which could be the way she responds to deflecting feelings of shame or other intolerable emotions.

The good thing here is that you spoke up for yourself. It's hard to feel dismissed, but I hope you're able to see that it's more about your mom than it is about you.
