Human nature
When you are sick, disabled, you have the opportunity to experience the surfacing of an ancient predator instinct in people. That’s when their aggression –verbal, or physical- is directed towards others who are weakened –the prey.
Maltreatment or abuse can come from various directions; whether from people whose job is to supervise if you are indeed in need of aid, or from a person you think you should be able to trust.
Nobody, in the prey position, is ready to give up. Assuming that they deserve what’s coming, is like accusing a woman of being guilty of her own rape because she was too sexy.
