Try not to worry about what is ahead. Accept that it's going to be a bit rough, so you'll remember to be patient with yourself and the team. You're in the physical hands of your surgeon and the nursing team now. And they've done this many times. Rely on your ostomy nurse because he / she will teach you how to care for and change your temporary bag. When you wake up from surgery, you'll have all manner of tubes, bags, and maybe a catheter for urine, sticking in your body. Remember that as each day passes, a tube will be removed, until you're no longer tethered to anything. Freedom! You'll only have the ostomy bag attached to you, and you'll become expert at changing it until you have your takedown surgery. Did you pick up a plastic bidet bottle? I packed mine for the hospital stay. That bidet will be your best friend in preventing Fire Bum. I also packed a pair of washable (or just dispose of) flip flops for walking (shuffling) around the hallway. Best wishes.
