I cant even ask where the toilet is.

I cant even ask where the toilet is. Last week, me and my family went to a little café. We were having a good time, but suddenly i need to go to the toilet, so i ask my mom where the toilet is, she says i need to ask someone that works there, but i couldnt do it, the anxiety was to much, i knew i was gonna mess it up, so i held it in. They asked why, but i knew they wouldnt understand. My brother was telling me the whole time to: just do it. But its not that easy. I hate my stutters.
