55 years male, tells family he will commit suicide, he has applied divorce recently, background: recovery agent for 4 years only after that was unemployed a long time, spend whole day watching crime story on news channel. Stopped alcohol 3 years ago, harasses family members mentally & physically from 20 yrs, stays away from positive people, only thinks of his own enjoyment, never gets happy if family member is successful, His parent never treated him with love in childhood, so has a lot of negativity in mind. Always listens to people who give negative suggestion to destroy family, only intension now is to destroy family members at any cost, family members still care for him. IS THIS A MENTAL DISEASE? Is there a treatment for this?
