I just recently got an ileostomy, and I feel the same way. I have a friend that promised me that she would be brutally honest if she could smell me. If she's not around, I always carry Bath and Body Works lotion with me, and rub some on my hands. Just so I don't smell that "smell" after I empty my bag, or release the "air" trapped inside my bag. I feel like sometimes the smell gets "stuck" in your nose, and that's all you can smell. Plus, I found I smell it more than anyone else because I am "smelling for it." I still am self-conscious about it, but every day I keep trying to find ways to make the "smell" less potent. Adding lubricating deodorant to your pouch definitely helps with the smell too. I use Coloplast Brava lubricating deodorant, and that helps some too.
I know this whole change is hard. Praying that every day gets easier for you too. It's definitely a change from the norm. Hang in there
