Abuse Mental
Abuse is a general term for the use or treatment of something (person, thing, idea, etc.) that causes some kind of harm (to the abused person or thing, to the abusers themselves, or to someone else) or is unlawful or wrongful. Its close synonyms are mistreatment and maltreatment. The word "misuse" has a more distant meaning of incorrect, uneducated use, not necessary harmful.
Abuse can be something as simple as damaging a piece of equipment through using it the wrong way, or as serious as severe maltreatment of a person. Abuse may be direct and overt, or may be disguised and covert.
