Hi, there is probably something bothering you at conscious or at Subconscious level. Stress may occur even without awareness. We adults think something is really not a problem... but our body especially sleep patterns are very sensitive to any disturbance in and around us.
Next Steps
Kindly see a psychiatrist to understand this at the earliest.
Health Tips
Sort help early to avoid long term disturbance. kindly dont wait... because 15 days of no sleep is a big break down...
