Why wish that your sibling had autism if you suffer from it? Isn't that kind of cruel? I don't mean to be harsh or offensive or something, just asking a simple question.
I also came here because I had nobody to talk about my problems with. Either it was because people didn't understand me or because I didn't dare to talk to people about it. I am not autistic but have my own set of problems and issues in life. Anyways, if you want someone to talk to, then know that people on PC, psychcentral, are very friendly and helpful in all ways. Also feel free to ask me anything. I am not an expert at anything, but I am a respectful listener.
I wish you luck, and greetings,
