Stress causes physical changes in the body designed to help you take on threats or difficulties. You may notice that your heart pounds, your breathing quickens, your muscles tense, and you start to sweat. This is sometimes known as the fight or flight response.
Once the threat or difficulty passes, these physical effects usually fade. But if you're constantly stressed, your body stays in a state of high alert and you may develop stress-related symptoms.

Depression is more than simply feeling unhappy or fed up for a few days. Most people go through periods of feeling down, but when you're depressed you feel persistently sad for weeks or months, rather than just a few days. Some people think depression is trivial and not a genuine health condition. They're wrong – it is a real illness with real symptoms. Depression isn't a sign of weakness or something you can "snap out of" by "pulling yourself together".
The good news is that with the right treatment and support, most people with depression can make a full recovery.
How to tell if you have depression
Depression affects people in different ways and can cause a wide variety of symptoms. They range from lasting feelings of unhappiness and hopelessness, to losing interest in the things you used to enjoy and feeling very tearful. Many people with depression also have symptoms of anxiety.
There can be physical symptoms too, such as feeling constantly tired, sleeping badly, having no appetite or sex drive, and various aches and pains. The symptoms of depression range from mild to severe. At its mildest, you may simply feel persistently low in spirit, while severe depression can make you feel suicidal, that life is no longer worth living.
Most people experience feelings of stress, unhappiness or anxiety during difficult times. A low mood may improve after a short period of time, rather than being a sign of depression.

PTSD (Post-traumatic stress disorder)
In our everyday lives, any of us can have an experience that is overwhelming, frightening, and beyond our control. For example, we could find ourselves in a car crash, be the victim of an assault, or see an accident. Most people, in time, get over experiences like this without needing help. In some people, though, traumatic experiences set off a reaction that can last for many months or years.
There are three main types of symptoms of post-traumatic stress disorder (PTSD):
Being ‘on guard’. You find that you stay alert all the time, as if you are looking out for danger. You can’t relax. This is called ‘hypervigilance’. You feel anxious and find it hard to sleep.
Social phobia involves a fear of embarrassment or humiliation in situations where you may be exposed to the scrutiny and judgment of others or you must perform. It is a fear of being with other people which can cause significant restrictions on the way in which an individual can lead their life. This can make it hard to eat out or speak to other people, particularly if you are meeting someone for the first time or at parties.
The most common form of social phobia is a fear of speaking in public. Other social phobias include:
People can also experience a number of physical symptoms such as a very dry mouth, sweating, palpitations, wanting to pass water or empty their bowels and a feeling of numbness or pins and needles in their fingers and toes.
Specific phobias are common and typically involve a strong fear and avoidance of one particular type of object or situation. The fear and avoidance typical of specific phobias can cause an individual significant distress and interfere with daily functioning and lead to increased anxiety.
Among the most common specific phobias are the following:
Specific phobias are often childhood fears which were never outgrown, may develop after a traumatic event such as an accident, natural disaster, illness or for example, being bitten by an animal. These may also develop from the repeated observation of a parent or primary caregiver who also has a specific phobia.
In general, people with OCD experience obsessions. These are thoughts, pictures or impulses which are usually unpleasant and come in to mind when we don’t want them. Many things can trigger these obsessions and they usually leave the person feeling very anxious, uncomfortable or frightened. The compulsion is the behaviour performed in order to “put right” the obsession.
Sometimes the behaviour is quite irrational, such as counting up in sevens for seven minutes. Sometimes the behaviour is more closely related to the obsessional thought such as washing hands many times to avoid contamination.
Most people with OCD know that their compulsions are irrational or “over the top”, but they feel unable to control their thoughts or change their behaviour.
OCD affects people in a number of ways, such as the following:
What we think:
How we feel:
What we do:
Most people who have OCD find that there is a pattern in their thoughts, feelings and actions. They feel anxiety or discomfort at having the obsession and relief once they have carried out the compulsive act. This becomes a vicious cycle which strengthens itself and becomes more likely to happen again.
Anxiety can feel like a fear and when it’s caused by a problem in our life that we can’t solve, such as money difficulties, we call it worry. If it is a sudden reaction to an immediate threat, like looking over a cliff or being confronted by an angry dog, we call it fear. Although these feelings are unpleasant, they exist for a purpose. Worry, fear and anxiety can all be helpful.
Psychologically – they keep us alert and give us the motivation to plan and to deal with problems
Physically – they prepare our body for sudden, strenuous exercise, to run away from danger or to attack it – the ‘fight or flight’ response.
These feelings become a problem when they are too strong, or when they carry on even when we don’t need them anymore. They can make you uncomfortable, stop you from doing the things you want to – and can generally make life difficult.
Some of the symptoms people experience are feeling worried, tired, and unable to concentrate, being irritable, sleep disturbance and feeling depressed. There are also a number of common physical reactions such as palpitations, muscle tension, breathing fast, faintness and trembling.
Although commonly known as a fear of open spaces, agoraphobia is where a person is afraid of being in situations from which escape might be difficult or help may be unavailable if you were to suffer from a panic attack. Situations can vary from individual to individual and examples can includes a fear of crowds, public places, enclosed or confined places, public transport or being at home alone.
The anxiety involved with agoraphobia arises from the anticipation that you might be stuck in a situation in which you would panic.
The most common feature of agoraphobia is about being far away from home, or far from a safe person, usually a spouse, partner, parent or anyone with whom you have a primary attachment.
This disorder can cause significant restrictions on the way in which individuals lead their lives and, because of this, people may also be depressed. Depression arises from feeling as though you are powerless and have no control over this condition.
