What do you suggest if i'm always tired and have bad headaches?

Some thots: Need to find out if "tired" due to sleep disorder, depression, low thyroid, as any of these can promote headaches, of either migraine type or tension type. Have a long discussion with your usual doctor and decide the next steps. Your problems are common and usually a successful outcome results from pinning down causation.

Multiple causes.: You will need a comprehensive examination and tests to rule out anemia, hypoglycemia, chronic EBV, autoimmune and STD illnesses. I agree that stress, tension, anxiety and depression can also cause these symptoms.
