What do you do....? Autism Parenting

What do you do, as an autism parent, when your son needs more help and understanding than people are giving him? It's the first month of school and he has been suspended, sent home and has been held from riding the bus on three occasions.
Let me back up a little.
We are living with family, big change.
He's in a new school, big change.
Nothing at this school is remotely like his old school, biiiig change.
Oh and he's 10 and going through some hormonal changes.
So, his whole world is upside down.
Maybe he needs a med change. But I feel this school might not be right for him. It seems as though they aren't trying to get to know him at all. I'm at a loss. We haven't had this many behavior problems in over a year.
I feel like it's my fault. Like my decision to move is what caused this. But again, he was fine all summer.
So what now?
Well for one, I stop blaming myself. It's not my fault and it's not his fault either. I'm not blaming anyone directly because its likely several factors and because...autism.
Now we are going to have an IEP meeting and will discuss more ways of handling the aggression and what may be triggering it.
I'm currently waiting on his doctor to return my call.
I brought him home and helped him calm down, now he's relaxing on his own.
My job is done for the moment.
There is nothing more I can do right now except...take care of myself. Go through my own feelings about what happened and then relax. That's it.
As autism parents we have to learn that some things are in our control, and others are not. And sometimes we can only control so much of a situation before we have to give it up because....autism.
I'm getting a soda and I'm going to chill until the doctor calls.
Because...mom needs a break.
