Kjs, I definately know where you are coming from when it comes to the computer and video games. I know this may seem like an odd question but which game is it that he is obsessed with? Computer issues are big here, with one currently going on.
He sounds incredibly frustrated, as do you. Reminds me of my difficult child and myself. Mornings are the worst and if not properly tended too end up with he leaving for school upset and stressed and me wanting to run away, things then spiral down for him at school. I have to agree with one of the posts in another thread that he seems to be trying hard to please you and get your approval. It's funny how much they want to please us and with that brings the stress, the anger, the hostility...I am guessing husband does not have the same problems with your difficult child as you do?
It also seems like the situation at school is stressful. If he is convinced that nothing is going right, he won't try. My difficult child will argue and backtalk when in trouble. Main thing we have tried to tell the teachers is to not engage. He's looking for a battle and when you feed into it, he looks for more.
Your family is spiraling down in a negative cycle. I agree with everyone that you need to deal with you first. When difficult child was at his worst, I was put on medications too. I was not helping him, I was what was making him worse. Secondly, you and husband need to be on the same page, if your not, it'll never work. At this point in time you both have to realize that this is about helping him. If his environment is hostile then you can't expect him to act any different.
I would also ask for the school psychologist (ours is from the school board) for any doctors or clinics that offer teaching skills for both parents and children that they can refer you too. Look up chapters or organizations that may be able to help with councilling or even babysitters so that you can get out for some you time.
I wish you all the best with the IEP meeting. Keep your chin up, you are doing the best that you can do. We all make mistakes and all we can do is try better the next time.
One thing I find helpful too is to make sure I tell difficult child at least one good thing about him and something great that he did each day, no matter how small. They need to feel like they can do something right.
Keep your expectations realistic. It's not easy with these kids.
