klmno - "Now that I think about it, I forgot to give him his medications this morning"
Bingo.
Jennifer - "*Can not giving the medication create that type of behavior so suddenly??"
Yep.
"having a PO that undermines my authority by trying to play family therapist and telling difficult child that I am just over-protective with him instead of backing up my authority and the rules of the house is worse than having no one to help at all."
Good for you. That PO doesn't live with you, he hasn't got a clue what you're trying to do (as in, HIS job as well, by the sound of it).
klmno - "He's back. I'll try to give him medications now."
It's all you can do. I do think it could be a factor, especially if you suspect his dosage is a bit low for him. That would mean that he would become symptomatic more quickly after missing a dose.
Hang in there. At least it's the weekend. As for this other kid - difficult child is 13. He's a babe. He's confused and at some level, even a kid who is trouble and a nuisance may feel better than being ignored by everyone. I think difficult child needs to talk to you about how he feels, about loneliness and about feeling useless and always in the wrong (of course, partly because he does stuff up at times).
Where does he go when he walks out? Is there somewhere on your property that would do the same job for him? difficult child 1 used to go climb our tallest tree (often dressed like a ninja) and just sit there, often in the dark. You couldn't even find him with a torch. But I could generally 'feel' where he was and if I listened carefully, I'd hear him fidget. Possums sound different. (my my, his wife is in for an interesting time... two weeks to the wedding and counting. Yes, it can happen for them.)
Hang in there. I know I keep saying that. Just get some extra-strength nail hardener onto your fingernails so you can keep your grip in the crevices on the cliff edge. And claw out the PO when you see him.
