Struggling to Express My ADHD to My Mom

I honestly don't know how to explain how I feel to my mom. She was there when I was diagnosed with adhd and has been here for me since but everytime I show any kind of sign I actually have adhd she tries to "calm me down" but it just makes me feel like I'm a bad person for showing my own disorder and it makes me feel like I'm not allowed to express it and most of the time when I'm not masking it's because I feel comfortable and I'm happy so it feels like she doesn't like to see me happy but I know that she doesn't know that this hurts me and thinks she's probably helping me in some way but it still hurts.
