Wendy,
Glad to hear your brother is on the mend finally and getting out. Can he talk with the ostomy nurse at the hospital where he had the surgery and ask for different appliances that might have a better seal so he doesn't have to worry about
leaks so much? Sorry to hear he's having trouble sleeping, is it insomnia or fear of a leak? Maybe it's best that he's not back to work so he can continue to gain strength and nap whenever possible, and take on smaller jobs at first?
He's been through a lot and it wouldn't be surprising if he's unable to return to work until after his final take down.
I think all of us had a hard time adjusting after surgery, but it will get easier for him in time and I'm sure there are people with permanent ostomies that work in similar fields. I think someone here on the boards said that they are not going to let the ostomy stop them from living a normal life and hearing that made me step out of my "comfort box" and do everything I did before the surgery. It's all about
acceptance and that comes with time, and at least I know that if my take down doesn't work out, I can still function perfectly with an ostomy.
Keep up the patience, your brother is lucky to have a sister that cares so much and I hope he continues to do well and his surgery is a success!
