We can talk about it right here, can't we?
I would go crazy if I couldn't make art, that's how I unwind. I art journal. I take online art workshops, because a.) it would be very difficult for me to make it to a regular class with my children's needs and b.) because of my own Aspie traits, if I can choose an activity that minimizes the face to face social component that is much more relaxing for me. Sometimes all I have time for is a few minutes a day, but even so in the end I create something that is all mine, no one can mess it up or take it away or complain that it tastes funny/feels weird/is too loud/hot/cold etc. Mixed media modern abstract is one of my main interests and outlets.
I also read voraciously (or listen to audio books when time for reading is scarce), and have a few friends that I keep in touch with online on a near daily basis (one of them has a teenage son with Aspergers). These things keep me sane and hopeful. I have something to look forward to every day, and people to share my interests and concerns with (without the stress and obligations of the people being geographically close).
My husband collects illustrative art, and does some web and book design. He has a website he maintains with his collection, and it has garnered quite a bit of attention and interest. This keeps him feeling happy and gives him a sense of accomplishment beyond the daily grind.
I really think us parents need our own interests completely separate from our children to stay healthy and happy. Sometimes it is OK to let the kids play video games/indulge in whatever their interests are while you take time for yourself...even if the house is messy or there are a hundred other things you could/should be doing. I think we need to be "selfish" and do things for ourselves regularly.
