😴 Always tired?

So I don't know why but I'm always tired get off work tired at work tired at home just woke up from a 9 hour sleep? Still tired. At the grocery store? About to fall asleep in line. Riding in a car? Taking a 5 minute nap if where we're going isn't just ride around the block. I'm not currently pregnant. I'm always hungry. Like I can eat something and still be hungry. Was laying down watching tv smelled my boyfriends Chinese about made me sick but I had ate some earlier that night. Smelled him eating candy started feeling sick again. I just don't know what wrong with me? Anybody have any good reasons whatsoever as to why I've been feeling this way? Thanks in advance ❤️
