Have Mental Health Questions? Ask a Psychiatrist Online
your question is seeking a subjective view :one's "feelings"/reaction to these terms. They do not have to apply to psychosis which would be marked mostly by hallucinations/delusions. The terms can apply to someone having a difficult time coping with something either situation such as death of family member, loss of job, terminal illness, etc. as well as coping with depression, anxiety and multiple stressors. The terms can also apply to someone who is not able to effectively deal with triggers such as how they display anger or behave towards others when angry/frustrated. It is not necessary for someone to suffer from psychosis or any mood/mental illness to display poor judgment hence, become tipped over the edge or like we say in the US "fly off the handle" Crimes of passion, mob mentality, etc can all be considered in that category.
