Yesterday, I intended, but didn't get around to suggesting that you ask your doc about possible reactions to the cricket droppings, since you stated that you and your wife are having similar symptoms. But this sounds more serious that that, obviously.
Warning, scolding ahead. I hope you haven't made a fatal mistake, but you've definitely made a mistake. Leaving the hospital AMA that way was a big mistake; please don't do it again! I get how you being away will be tough on your wife; think of how tough it would be on her if you're gone for weeks or forever. Surely there are friends who could have moved the car home and looked in on her. Don't be a fool (again)!
