Hey Amy - Hugs. If it's not one thing it's another. If you can, request to have the school psychologist there when you meet at school. If you have any paperwork that diagnosis your son, bring that too. They should be able to work with you and your son during this time not burden you more - we see this all the time in my school and allowances are made all the time (and I teach on the high school level.)
In regard to visiting your H, I too see both sides of that issue. My gut says, go see him - but not for yourself - for him and for the future of the relationship the two of will have to have for the sake of your kids (regardless of whether or not you stay married). IMO, you do not want to be in the position where anyone can say (including yourself) that you didn't do what was needed to save your marriage or help your H. That being said, do not go for the sake of working out your M, go because a sick "friend" asked you to go. You don't have to stay long - 5 minutes maybe, but just show up. Don't give yourself enough time there to discuss anything or get accused of anything, say hello, get well soon, call me when you're better, the kids miss you, bye. Hugs
