I know it's hard, but you need to relax. Really, truly if you've washed your hands after going #2 and spray down the flusher and the sink handles you really are ok and your mom is going to be fine. You don't need to keep cleaning and doing laundry. Go to bed and get a good night of rest.

As for where you got it, I think your brother's baby may have passed it on to you. I really doubt it was the apple. I eat unclean fruit ALL OF THE TIME and haven't ever caught a bug. If it was, that would just be poor luck. No matter what, it's over and done with. Stop looking it up on the web.

Everyone is going to be ok, you're going to be ok. Get a good night of rest and tomorrow you'll be all that much happier when you are well rested and this ordeal is one more day behind you!
