Im really sorry your day has not gone as well as you had hoped

I always try and question why people behave or act the way they do. Other peoples behaviour can be very...frustrating. But when I try to empathise with them, it helps me potentially see things from their point of view.
Its difficult to do in the moment, but it really helps me. Maybe trying that would help you? I dont know, its just a suggestion.

Saying that, we all have bad days and we all have days when we've had enough, we're only human.
