My sleeping schedule is so fucked up what should I do?

Have your parents schedule an appointment with your family doctor. When the doctor asks what brings you in today show them what you have written here. Use that as a basis for having a frank discussion on how you are doing. They can do a full physical and neurological workup to see if anything you are taking or doing may be causing or contributing to your issue. They can refer you to sleep specialist for a sleep study. Your doctor can also refer you to a mental health professional that can evaluate your mental state. Once the test results are in, treatment options can be discussed.
