Insomnia is the inability to fall asleep.
Want of sleep; inability to sleep; wakefulness; sleeplessness.
The inability to breathe temporarily is called apnea. Periods of apnea during sleep, particularly those causing intermittent, frequently subconscious awakenings, is called Sleep Apnea. Sleep apnea comes in various forms. The most common being Obstructive Sleep Apnea (OSA). This is caused by an obstruction of the hypopharynx and glottis during sleep - usually the soft tissues of the mouth, soft palate, and throat relax during sleep and occlude the airway. Central Sleep Apnea (CSA) is rarer and caused by neurologic, toxicologic, and metabolic disorders.
The opposite state from sleep is waking, to be awake. The opposite (inability to sleep) is insomnia.
That is the correct spelling of the term "insomnia" (inability to sleep).

There could be several reasons why you have been so exhausted. It could be that you are just not getting enough sleep, or it could be that you are under a lot of stress. If the exhaustion continues, it is best to see a doctor to find the cause.
