Could be. Go to see your primary care doctor and she/he will have to run some blood work to confirm the presence of anemia and if so- to find out the cause. Some other conditions besides anemia- like chronic disease- thyroid, hear, lung, kidney, dm, depression, etc, sleep problems/osa- also can give you fatigue, feeling sleepy etc. Teatment will depend on the problem. Good luck.
