Hello Mrs Bennett
Yes I suffer with random anxiety too thanks to fluctuating hormones and it has definitely made my bowels looser. My anxiety manifests by causing tingling/****ling sensations down the middle of each buttock and down toward the backs of my knees. It's not exactly unpleasant but I would rather I didn't have it. When it's particularly severe I can guarantee that within a few minutes I will need the loo.
These ****ling sensations start the minute I wake up and I think it's become almost a bad habit for me now. Because I am expecting them to start when I wake up they DO start if that makes sense? Then they can happen randomly through out the day.
Have you considered wearing something like a Tena pad, just as an insurance against soiling yourself.
