I’m having multiple problems, what could it be?

I don’t know where to start exactly, so I guess I’ll just jump in. Most of these symptoms have developed within the past two years. I’m chronically tired, to the point where I’m sleeping 8 hours a night, still falling asleep at work & taking 2-3 hour naps when I get home, even with taking prenatal vitamins (I’m a male). I have constant problems with my bowels, stool goes to hard to runny in the blink of an eye, abdominal and groin pains, constant sinus infections and blockage so bad I have to breathe through my mouth (I have had this my whole life), extremely decreased sex drive, I begin sweating as soon as I’m out of the shower (just under my armpits) and am normally soaked within an hour no matter the temperature, bad breath that even after tongue scraping and brushing is still there and not to mention my teeth have went from nearly perfect to needing full mouth restoration in under two years (never did meth or anything like that). Oh, and I’m only 20 years old. Help!
