Common diagnoses of mental health conditions
Depression lowers your mood, and can make you feel hopeless, worthless, unmotivated and exhausted. It can affect sleep, appetite, libido and self-esteem. It can also interfere with daily activities and, sometimes, your physical health. This may set off a vicious cycle, because the worse you feel, the more depressed you are likely to get. Depression can be experienced at different levels e.g. mild or severe, and can be related to certain experiences; for example, postnatal depression occurs after childbirth. Depression is often associated with anxiety.
Anxiety can mean constant and unrealistic worry about any aspect of daily life. It may cause restlessness, sleeping problems and possibly physical symptoms; for example, an increased heart beat, stomach upset, muscle tension or feeling shaky. If you are highly anxious you may also develop related problems, such as panic attacks, a phobia or obsessive compulsive disorder.
Obsessive-compulsive disorder (OCD) has two main parts: obsessions and compulsions. Obsessions are unwelcome thoughts, ideas or urges that repeatedly appear in your mind; for example, thinking that you have been contaminated by dirt and germs, or worrying that you haven’t turned off the oven. Compulsions are repetitive activities that you feel you have to do. This could be something like repeatedly checking a door to make sure it is locked or washing your hands a set number of times.
A fear becomes a phobia when you have an exaggerated or unrealistic sense of danger about a situation or object. You will often begin to organise your life around avoiding the thing that you fear. The symptoms of phobias are similar to anxiety, and in severe forms you might experience panic attacks.
Bipolar disorder (formerly known as manic depression)
If you have bipolar disorder you will experience swings in mood. During ‘manic’ episodes, you are likely to display overactive excited behaviour. At other times, you may go through long periods of being very depressed. There are different types of bipolar disorder which depend on how often these swings in mood occur and how severe they are.
Schizophrenia is a controversial diagnosis. Symptoms may include confused or jumbled thoughts, hearing voices and seeing and believing things that other people don’t share. If you have these symptoms you might also become confused and withdrawn. There is debate about whether schizophrenia is actually one condition or more a collection of symptoms that are not clearly related.
Generally speaking, personality doesn’t change very much. Yet it does develop as people go through different experiences in life, and as their circumstances change. If you have a personality disorder, you are likely to find it more difficult to change your patterns of thinking, feeling and behaving, and will have a more limited range of emotions, attitudes and behaviours with which to cope with everyday life.
Eating disorders can be characterised by eating too much, or by eating too little. If you have an eating disorder you may deny yourself anything to eat, even when you are very hungry, or you may eat constantly, or binge. The subject of food, and how much you weigh, is likely to be on your mind all the time. Your eating disorder is likely to develop as a result of deeper issues in your life and is possibly a way of disguising emotional pain. Anorexia, bulimia, bingeing and compulsive eating are some of the most common eating disorders.
In addition to the more formal diagnoses above, there are some behaviours and feelings which are strongly associated with mental health problems.
Self-harm is a way of expressing very deep distress. You may not know why you self-harm, but it can be a means of communicating what you can’t put into words, or even into thoughts, and has been described as an ‘inner scream’. After self-harming, you may feel better able to cope with life again, for a while, but the cause of your distress is unlikely to have gone away.
It is common to have suicidal thoughts if you are experiencing mental health problems – especially if you have a diagnosis of depression, borderline personality disorder or schizophrenia. The deeper your depression, the more likely it is that you will consider killing yourself. However, you can help yourself and you can get help from other people. A great many people think about suicide, but the majority do not go on to kill themselves.
These are sudden, unexpected bouts of intense terror. If you experience an attack you may find it hard to breathe, and feel your heart beating hard. You may have a choking sensation, chest pain, begin to tremble or feel faint. It’s easy to mistake these for the signs of a heart attack or other serious medical problem. Panic attacks can occur at any time, and this is what distinguishes them from a natural response to real danger.
