Depression is low mood that lasts for weeks or months and affects your everyday life. It can cause a variety of symptoms.

For example: lasting feelings of unhappiness and hopelessness, feeling tearful, losing interest in things you used to enjoy, tiredness, sleeping badly and poor appetite.

The symptoms of depression range from mild to severe.

This means having regular or uncontrollable worries about many different things in your everyday life.

People with Generalised Anxiety Disorder feel anxious most days and often struggle to remember the last time they felt relaxed.

As soon as one anxious thought is resolved, another may appear about a different issue.

This condition can cause a range of symptoms, from feeling restless or worried, trouble concentrating, sleep difficulties, tension, dizziness or heart palpitations.

Spending so much time worrying about your health, or getting ill that it starts to take over your life.

People might frequently check their body for signs of illness, such as lumps, tingling or pain, ask people for reassurance that they are not ill, worry that their doctor or medical tests may have missed something, obsessively looking at health information, avoid anything to do with serious illness, or act as if they were ill (for example, avoid physical activities).

Anxiety itself can cause symptoms like headaches or a racing heartbeat, and this can be mistaken for signs of illness.

People develop a general image of themselves based on past experiences, often beginning in childhood.

This may be due to being criticised or not receiving sufficient praise and can result in them believing they are worthless no matter how well they do as an adult.

People with low self-esteem often expect others to  judge them negatively, as they tend to have unreasonably high expectations of themselves.

This is not a mental health problem in itself, but will often be part of other mental health difficulties.

Panic is an anxiety disorder in which panic attacks occur unexpectedly and frequently without a clear cause or trigger.

The attacks are sudden periods of intense fear that may include palpitations, sweating, shaking, shortness of breath, numbness, or a feeling that something terrible is going to happen.

Some people may feel constantly afraid of having another panic attack, to the point that this fear itself can trigger one.

This is an anxiety disorder that a person might develop if they have been involved in or witnessed a traumatic event.

It was first recognised in war veterans, but a wide range of traumatic experiences can trigger this condition.

There are a number of symptoms associated with this condition such as flashbacks, feeling numb and trouble sleeping.

These are sometimes described as an ‘acute stress reaction’. If a number of the symptoms continue for longer than a month then a diagnosis of PTSD may be given.

Distressing thoughts, images or worries that something bad will happen if you do not do a certain action.

For example, needing to repeatedly clean the kitchen to prevent your child from getting ill or the needing to arrange items in a certain way otherwise something bad will happen to friends or family.

Extreme fear or anxiety triggered by social situations (such as parties, workplaces, or any situation in which you have to talk to another person).

It is also known as social phobia.
