Most of all, I have learned to except that this is going to happen to me. People can judge what they want, and yes its very embarrasing - but I can't control it, so I try my best not to feel guilty about it. For example, 2 weeks ago on a gorgeous sunny afternoon I really wanted to head outside to take some photos along the shore. I felt "ok" so convinced myself all was fine, and headed out. 10 mins later I was out on this goreous rocky beach, with a few people along the shoreline near me, when I got the "OH NO" sensation. There truely was no place to squat, no bathroom to run to, nothing. So I pooped my pants (I had a pad on). Then i finished taking the photos I wanted to get - headed back to my car - avoiding people 'cause I felt soooo stinky and headed home to a shower and clean clothes.
Not an ideal day - but at least I got out.
