I poop out of a tube so if I have gas come out it sounds like nothing else anyone has heard. So I sometimes hope I get gas in public stalls, so the person next to me can think "WHAT THE HELL WAS THAT"?! I sometimes just laugh when I am going to the bathroom now. I turned into a 4 year old.
I had a lot of anxiety when I had a colon though. The smell mainly but I guess that is a normal girl thing. I don't have smell anymore so some anxiety is gone over that.
There is a lot worse that can happen in life is how I see it lately and we all went through hell with these surgeries so just try to relax and carry on
It is a 5 minute thing that happens, wash up and get out.
but if it helps and you have an iphone or android there is an app that makes water noises, etc. It is for IBD suffers actually that you can play in the bathroom to help with the anxiety.
