I have schizophrenia and was in a big episode this year. I got so paranoid and stressed in public that I always almost shat my pants. Literally. Thankfully I never shat my pantalones but it was always very close and the stress gave me  diarrhea that put me in the toilet every time I built up the courage to leave my flat. In retrospective I can laugh about it and wanted to share this. 
Thank you for reading this and I am open for questions or related things in the comments
