IIN that i have this big fear of being stuck/locked behind a door in a bathroom or in a changing or fitting room? , that's why i never lock the bathroom door nor the changing room , unless the lock is very easy to unlock ,but even if it is .. i am scared of locking it .

This might sound kinda weird. But I used to always think up plans before I would go into public restrooms in case the door does get a little stuck. Like when I was younger, in a bathroom stall, I knew if the door got stuck I could always crawl under the opening at the bottom.
I cant go to the [public] toilet by myself, especially if theres no window!
