Stress, anxiety and depression are common mental health issues. They have a range of symptoms, which can be mild or severe.

Stress

Feeling stressed is a natural reaction that can help people get things done or be more motivated. For example, knowing the science test is on Monday may cause a student to feel stressed, but it will also motivate them to revise on the weekend.

When stress is constant or unmanageable it can become a problem and cause the following symptoms:

  • Physical symptoms such as aches, dizziness or stomach problems.
  • Changes in behaviour such as being snappy, forgetful, difficulty concentrating or making decisions.
  • Increased worrying, feeling overwhelmed, difficulty sleeping or eating.

But anxiety occurs when these feelings are more constant. The symptoms include:

  • Feeling restless or worried.

  • Lasting feelings of unhappiness and hopelessness, feeling very tearful, tired and sleeping badly.
  • Losing interest in the things you usually enjoy.
