All this movie business seems to cause you much drama, negative experience and pain. I understand it was wrong of them to block you but I personally prefer to avoid dramatic situations because life is just too short.

For whatever reason all these people don't want you to be in their movie sets and do not want you to tweet, post, call, leave messages, email etc I don't know why and it's possible they are being very wrong. But you can't control it. You can't make them do what they don't want. You can only control yourself ( i understand it's not easy especially with ASD).

Could you find different activities that would give you more positive experiences? Something uplifting?
