Don’t always believe what “people say.”People say, autistic people need you to sit dem down and tell them exactly what you want.
You should always be clear with everyone about what you want, but we do not need to be sat down and spoken to like children.
Crying and screaming is a desperate way to communicate. It is not typically very effective.
You can only control yourself. Perhaps, you could benefit from some mental health support. A therapist could help you learn how to set appropriate boundaries. I don’t think it’s working, the way you are going about it.
