I’m working in a professional environment at this very moment (for the next 15 minutes anyway). It’s not other people’s job to know your triggers. It’s your job to deal with them or seek other employment. Like working from home where you don’t need to deal with people.

If someone was raped on a blue couch, that doesn’t mean it’s everyone’s job in the office to avoid the color blue. That’s is one of those things that YOU need to get over, or file for disability because you’re incapable of being in a work environment where anything might set you off.
