No one wants to leave you out in the cold, wondering what to say, facing a prickly pear of a pal who may even be immersed in a minor depression of her own.
Take the following advice and you should be fine.
DO NOT offer pity.
Nothing makes a girlfriend want to run off and take a shower (and then stay far, far away from the source of the filth) like genuine, heartfelt pity.
"You poor thing, I feel bad worrying about my (plumbing problems, child's broken wrist, difficulties at work) when I think of you!"
Of course your friend has it rough. But pointing that out and covering her in "You have it so much worse than me" slime only serves to rub it in.
DO NOT attempt to provide inspiration.
Don't tell her about the person you read about in the paper who performs on the piano or the family whose child is "completely recovered." Whether it is savantism or cure (or any other amazing gift of good luck), the reality is that most people with autism will not develop skills that allow them to "triumph" over their challenges, and recovery is as unlikely as lightening. Try to imagine telling your friend whose house just went into foreclosure about the woman in the paper who won the lottery. Would that help?
For every instance of those rare things happening, there is a reporter waiting to rave about it and a further five people sending the article to your friend. You don't need to be one of them. She may be struggling with her child's potty training, sleeping problems, lack of speech, intense unhappiness or daily living skills. Her child might grow up to be challenged to play the radio for an audience without driving them crazy by changing the station every three seconds. Trust me when I say that she will not feel inspired by the teenager with autism who plays concert piano.
DO NOT give advice.
If the parent of a child with autism is in the market for information, there is a great deal to be had. Most of it is garbage. You may read about secretin, chelation, elimination diets, or lyme disease. And there is credible information like new research underway. But assume that your friend has access to the information that you have access to, because she does. Forcing her to express gratitude for the exciting news that a new snake oil has arrived on the scene, or having to debunk it for the benefit of someone who doesn't really need it anyway is trying. Instead, be her respite from that part of her life.
DO (Please, please do) offer kindness and solidarity.
You may not know what this hardship feels like, but presumably you know what some hardship feels like. You want to strike a chord of "I know I can't truly understand this, but I'm behind you all the way. You go, girl!"
DO (Please, please do) listen.
Tune in and find things to ask questions about as if you are paying attention. "Last time we talked you were working really hard on getting insurance to come across. Any luck?"
DO (Please, please do) stay put as a friend.
Maybe your kids don't really like playing with her kids, but you can make them. Really, you can. You can insist. Eventually they will either find that they are enjoying it more than they thought they would, or it will be over. It is good for your kids to learn kindness and patience. It is good for her kids to play with your kids who don't have autism. But only you can make it happen.
DO (Please, please do) be patient.
It is entirely possible that your friendship will seem different, especially during the early years after a diagnosis. Maybe all her new friends have kids with autism and you feel weird, out of place. Maybe she has a tendency to cry over coffee. Work through it. She needs you. And someday, when you need to find a specialist for your child, you will call her first because she is so darn plugged-in to the local medical community and you can trust any recommendation she makes.
