Symptoms of mental health difficulties

The symptoms related to a mental health crisis can affect individuals in a variety of ways.

  • When experiencing psychosis, some people feel highly agitated, anxious or in despair, have suicidal impulses or the need to self-harm, are immobilised by depression, or are frightened.
  • Others feel confused or delirious because of an infection, overdose, illicit drugs or intoxication with alcohol. Confusion may also be associated with dementia.
  • The crisis may be a sudden deterioration of an existing mental health problem, or a person may be experiencing mental health problems for the first time.

Crisis means they need immediate expert assessment to identify what the best care should be and prevent further worsening of their mental wellbeing.

If you are supporting someone in this situation, it is natural that some of their behaviours may worry you. It’s fine to talk about suicidal and self-harming thoughts and it does not mean they are more likely to act on them.
