Practising a martial art/meditation helps many people with AS stay calm and keep from being overwhelmed. I do t'ai chi, and my son does aikido. Going someplace peaceful is always better for me than going someplace stressful, like an amusement park or a city.
My son has an AS diagnosis. He learned everything he could, then informed me that I met all the criteria for AS, too. I have to agree with him, although I can't afford to get formally diagnosed. Once my husband accepted that I probably have AS, it improved our marriage. Things he thought he was doing wrong, or was doing wrong, he now puts down to differences in communication styles. For example, it used to drive him crazy that I never asked him something directly, like for a glass of water. Now he realizes it's just the way my mind works. I make more of an effort to be direct about my wants and needs, but it is difficult, and when I'm tired or stressed, I forget.
On the other hand, sometimes my husband feels a little left out,like when our son and I are talking about the fine points of grammar, or when to use a semicolon. (Luckily, my son and I have a shared interest in languages and English grammar, without which we might not be as close as we are.) Other times he feels shut out by the way we communicate on a different level than neurotypical people do. On the whole, we are blessed to have such a sweet, supportive husband and father. He loves and accepts us just the way we are, too.
