I know people are not ignoring me on purpose. It's just frustrating. This is a real issue for us, it took courage for me to even ask the question on here, and I was hoping for some support and getting literally nothing. I'm an impatient person, but I really think this thread would have gone unanswered forever if I hadn't spoken up.

The problem is simple. It's solving it that's difficult, since some of the basic tactics don't seem to work very well.

You don't have to be in the exact same situation as I am to offer some kind of advice. So what if you don't have a sibling who has autism? I assume (foolishly?) that if you are browsing in the autism forum, you probably have some experience with autism. That's all the "expertise" I'm looking for. I asked whether anyone had a similar situation, but it wasn't meant to exclude everyone who didn't. And by the way, I hate the label "high functioning" because it implies that everyone not in that category is "low functioning." When my brother was diagnosed, that label didn't exist.
