What to do if i have never been this bad or long so what is the cause in my change of sleeping pattern?

Behavior modifying: One place to start is practicing good sleep hygiene. Keep your sleep pattern consistently structured, avoid napping, use bed only for sleep or intimacy, and avoid lying in bed long periods without sleeping. If falling asleep is troublesome because of trouble turning off your thoughts, relaxation and imagery techniques are often helpful. For more help with these make an appointment with a therapist.

Sleep Hygiene: Proper sleep hygiene habits which include set bedtimes and rise time, avoidance of alcohol, tobacco or caffeine within 5 hours of bedtime, no watching TV in bed, reading in bed, eating in bed, pets in bed or watching the clock during periods of being awake. Also avoid daytime naps as this contributes to inability to sleep well at night. Consider seeing a sleep doctor to discuss using a sleep diary
