Hi, Cathy, and Bienvenue! I originally hail from the big red stick a little north of you (I think).
Maybe our children were twins separated at birth? I don't have any tips to offer you, since I can't "handle" my son. The only thing I've learned is how to handle myself and my surroundings.
While things aren't "good" by any means, they are better since I've given up trying to directly control him. Like your son, my son is suspected ODD. We've learned to avoid the "rage triggers" that bring on an ODD meltdown. That doesn't mean we don't deal with him when we need to. We just have to find another way than a frontal assault (which was the way I was for a long, long time - my travails with my son broke me of my type A personality).
And, it's only been recently that I've started to be able to separate myself and my life from his choices and his consequences. Not really good at it yet, but I'm learning.
I'm very sorry to hear that your son has such a rebellious streak. While my son can still bring both me and my wife to tears with his actions, he has yet to be as defiant as you describe your son. I can only imagine the turmoil and pain his actions must bring. But it sounds like you've found at least a couple of groups that can help you. Have you been to an FA meeting, or just to the website? I've thought about attending, but haven't gotten to one yet.
I'd like to hear your story, when you have time to post it. My story is pretty much "out there" (I like to write - it's my way of dealing with my life). Also, you may want to fill out your signature with a little more information about you and whatever family members you want to share with us (furbabies welcome too!)
Again, welcome to our board.
Mikey
