Signs and symptoms of a nervous breakdown

3-minute read

There are many different signs that indicate a person may be experiencing a nervous breakdown. While not a medical term, people use this expression when referring to someone who is being overwhelmed by mental health issues.

Some signs relate to a person’s mental state and how they are feeling, or changes in personality. However, physical symptoms are also common. Signs vary from person to person, and can depend upon the underlying cause.

People who feel they are having a nervous breakdown can:

  • feel isolated — disinterested in the company of family and friends, or withdrawing from usual daily activities
  • feel unable to concentrate — difficulty focusing at work, and being easily distracted
  • be moody — feeling low or depression; feeling burnt out; emotional outbursts of uncontrollable anger, fear, helplessness or crying
  • feel depersonalised — not feeling like themselves or feeling detached from situations
  • have hallucinations — vivid flashbacks of a stressful or traumatic event can be associated with post-traumatic stress disorder — you should discuss any hallucinations or flashbacks with a doctor or counsellor
  • feel paranoid — believing someone is watching or stalking you
  • have thoughts of self-harm — if you have thoughts of self-harm, get professional help immediately

Physical symptoms can include:

People who are experiencing a nervous breakdown may avoid social functions, call in sick for work and isolate themselves at home. They may not be eating or sleeping properly, and they may not look after their personal hygiene.

If you are concerned that you or a loved one is experiencing a nervous breakdown, it is important to seek help and to see a doctor or counsellor.
