I never had a problem with being in this kind of situation before I was integrated (before I and my alters became one whole person again) the way my system was set up is any time I encountered a trigger (anything that made me feel like you posted) I would dissociate and another alter would take control and deal with the the situations that I could not deal with.

that said after integration sometimes situations like this would cause me problems because I no longer had alters to switch into. how I handled this kind of situation was going to the restroom. the body and brain are an amazing thing, you cant control bodily functions. when you got to go you got to go, its a normal fact of having a human body that eats. if something goes in the digestive tract the left overs must come out by way of the digestive tract. so going to the restroom while out in public is a completely normal thing human beings do. because its normal thing everyone does doing so doesnt reveal any secrets.

suggestion talk with your treatment providers, they will be able to help you make a plan of action that is right for you, for the next time you are in this situation.
