Everyone has changes in their mood and there are good reasons for these mood changes. If you have just had dinner with friends you may feel happy and if your pet has just died you may feel sad. Usually our mood is suitable for what is happening in our lives. People who have mood disorders tend to have big changes in their moods for no obvious reason. They may be excited or happy for no reason or upset and sad when good things are happening in their lives. When severe mood swings keep happening without good reason it is likely that the person has a mood disorder.
