I always feel stressed and not able to sleep in daytime and wake up early in the morning. My heart beat keep pulsing fast. Suggest me treatment. I am male 19yrs old.

Suggest you see doctor.

You need a doctor to take a medical history, and perform any tests or treatments that will identify and address the root causes of your problems. Are there any major issues going on in your young life? Why are you trying to sleep in the daytime?
