I am an adult who lives with sensory processing disorder, and I have to say it is not easy. It very much made my childhood very hard, specifically school was a hellish experience. I really feel for your daughter, and no doubt what you have to go through to support her. It's not easy.
I remember so many times when I was doing my absolute best to function the best I could, and strangers assuming my parents were not discipling me, or that I was somehow non-compliant, rebelling, being stubborn, or plain out disrespectful. I am none of these and my parents knew it. They did very much push me to do my best and work really hard, and I have very strong self-control, patience, and discipline. I mean I had to, I learned it everyday with SPD.
People love to Mom shame. No matter how well you parent, there are people who will believe it is their right to judge your parenting style, nothing will ever be enough for them. The whole world believes it is their job to educate, judge, and critique every mother they see, even if they have never had kids themselves. Also, they've never had your child.
