When Boundaries Are Crossed: Dealing with Overwhelming Feelings

Oh yeah, my autistic brain likes things in a very specific way and I am not shy about getting irritable and shutting down when ppl mess with my very carefully constructed environment

100% feel this. I tend to overreact about things in my personal space changing (for example my sister and I share a car and she keeps wanting to change things about the car/modify it and I get really frustrated with her bc of it) my best advice is to talk to them and set those clear boundaries. try to work with them and explain why it's important to you
