I'd add a few to the article---the tension that the autistic child creates in a household, that leads to everyone being on edge and more prone to fighting, the endless cleaning up of the messes the autistic child makes, the media finding a new way every day to point out how you inadvertently caused your child to be autistic, the few unkind strangers who make going out in public a minefield, the sadness from not ever being able to give your other children enough time, the worry about what is happening to your non-verbal child when you aren't with them...I probably could go on for a good long while.
And so I don't think it's strictly right to call what other parents and I often feel "depression". I call it more...a logical reaction. Tonight it is feeling that way, anyway. Back to trying to be upbeat next time, I promise.
