MWG, Sorry to hear that you are having a bad time still. I don't have any advice about the sore feet or the kids not doing chores or treating you with respect; hopefully you can find something that will help in all cases.
Your S is saying he is an adult? Okay, this is NOT parenting advice, it is just me expressing my feelings, and not saying YOU should do this...I think if I were in your sitch with S, I'd very quickly get fed up enough to say, "Okay, you want to have the privileges of adulthood, make your own decisions, do as you please? Fine, but you have to accept the responsibilities. That means you pay out of your own pocket for your housing, your transportation, your health/home/auto insurance, your groceries, your utilities, your lawn mower, your education...you figure out how to do your own taxes, your own home maintenance, cover your own retirement and savings plans, look after your own health...you can't separate rights from responsibilities; it's a package deal."
Okay, rant over. Jeesh, between your H and your kids and their friends, it's a contest to see who can yank your chain the hardest...! I am sure you will figure out a solution sooner or later! In the meantime, I'm thinking of you and hoping things improve!
Peace, Dawn
