Hi,
Have a look at this and see if you feel it applies to you.
Insomnia is classed as a sleep disorder brought on by an inability to sleep or the inability to remain asleep for a prolonged period of time. Insomniacs typically complain of being unable to close their eyes for more than a few minutes at a time. Both types of insomnia constitute as a sleep disorder. Insomnia is often caused by fear, stress, anxiety, medications, herbs, caffeine, depression, Bipolar disorder or sometimes for no apparent reason - it can also be linked to a poor quality or cheap bed. An overactive mind or physical pain may also be causes. Finding the underlying cause of insomnia is usually necessary to cure it.
