BeanieBaby, my 12 year old son has struggled in school since day one. Fortunately, now in middle school, he seems to have turned the corner and is finally "getting it" and catching up. What a relief!
I sobered up when he was in 4th grade. If I hadn't, neither one of us would have made it through 5th grade! It was a particularly difficult year with a lot of work needing to be done at home.
I'm reiterating what's already been said. Not drinking will help you deal with everything, especially organizing and doing the schoolwork.
It sounds like you have a lot of plans in place - you need to execute them.
