Hello doctor , i just want to know what should i do when i m feeling tired all the time , and for the information i spend almost half of the day sleep?

Start with doctor: There are many causes for fatigue and excessive sleeping. See your pcp for exam, appropriate testing and guidance. Write down meds you take including OTC, any alcohol/drug/caffeine/tobacco use, current stresses and about when problem started. First rule out medical causes for your fatigue. If all is normal, ask for referral to a mental health professional to assess for depression. Hope this helps.
