I got depression and slipped for ~3 years because of a difficult client. Since then, I always carry the big stick and use it all the time, in professional and non-professional situations. Let's say I got allergic of BS, and better you hurt than me getting anaphylactic shock. To get angry when there is a mess-up is not to be difficult. Difficult clients are more like abusive partners. They create the situations that allow them to exert abuse e.g. ask you to drop other clients, then ask for an impossible deadline, then assign side tasks all the time while pretending they don't know this will impact the deadline, then withholding payment, while saying that $1M is just around the corner.
