Can't sleep until 1 or 1:30 need to be up by 7. have been for almost two months. i'm tired all the time but i can't get to sleep. should i be worried?

Concerned: Please practice good sleep hygiene( google this if necessary). Avoid using iphone, computer, tv after 8pm or get blue blocker sunglasses to wear while looking at them. Take melatonin 3 mg 2 hours prior to desired sleep onset. See your family doctor to rule out common physical causes and to evaluate you for depression or generalized anxiety disorder. Input from a sleep specialist or psychiatrist could be helpful. Best wishes.
