The Cherry Plum type is like a pressure cooker with no release valve. They keep on bottling up their frustration until one day they explode. And yet, they are afraid to let their frustration out because they are fearful of what will happen.
Very often, such frustration might manifest as ill humour and facetiousness. It's not untypical for the Cherry Plum type to have visions of stabbing someone with a knife, or wielding an axe in his frustration.
For Empaths:
The Cherry Plum Empath may often catch themselves thinking violent thoughts. They may find themselves imagining throwing a knife at somebody, or perhaps blowing something up.
Not that this empath is violent. It's the opposite. It's repressed frustration that leads to anger, which leads to rage which will eventually lead to an explosion and health problems.
