Oh bloody heck Shell, do you have anyone - a neighbour? - who can come stay with you for a few hours or check on you. Please promise to post on here asap tomorrow morning so we know you're OK!
And poor Luke and what a worry for you all. Tim must be really torn wanting to be in two places at one time
Sending loads of feel better vibes to you and Luke and hoping you both feel better by the morning.
And Shell, promise you'll call the emergency services if you feel funny - please! (((hug)))
