The first time the wound nurses wanted to show me how to empty mine, they showed up right before my husband and kids were going to visit me in the hospital. My kids hadn't seen me since the night my perforation happened; it had been about two weeks.
It didn't go super well; they had me empty into a container and it was liquid - spilled on myself and the bed. Cue the panic.
So when they came in the next time to teach me how to change the bag, I wasn't having any of that - I did a fantastic job of changing my bag with my shaking hands. I didn't want to panic again.
When I got home, I did panic, but my husband said he'd be there to support me. He stood there and handed me stuff, but I did it. Then the home health nurse came - and she told me she had people on her rotation that just refused to even look at their stomas so she had to come change them regularly. I told myself I couldn't be dependent like that. You just gotta do it.
I recommend changing bags when you shower. I clean my stoma with just the shower head most of the time, in the shower, easy cleanup, no mess, no laundry. Pick a time when your output is low if you can, so you can get clean, then get dry, then measure your stoma (every time), cut your sticky thingy, and get it on without surprise output.
Oh, I call it output. Poop comes out my bum. Output comes out my stoma. Easier to talk about.
