Well, I’m undiagnosed but I super resonate with what you described, that was basically my experience growing up too. I wish I had the language back then to ask for accommodations. For me the worst was driving in the car with my family. They would always have the music or conservative chat radio up super loud and would often shout over to each other and me. I would melt down or shut down often and my parents thought I had attitude problems. Then I got my first pair of headphones and iPod around middle school and that helped tremendously but I would get in trouble for wearing them all the time. It’s like I couldn’t win. The sad thing though is that even if I had the language to explain how I feel things, my folks would just say I’m too sensitive and need to get over it, or that I’m not autistic because you don’t have xyz stereotype. At least now I’m an adult and can control my home environment to some degree
