Menopause Symptoms Facial Hair

It started last year when I was 17. Here are the following physical symptoms that suddently appeared: Oily skin, facial hair, weight gain, went from never sweating to excess sweating, gas, bad b.o., and lastly, and increase in my breast size.

Now this year most of the physical symptoms have subsided (aside from the facial hair and sweating) but I have experienced, in my opinion, a complete shift in my personality. I used to be appreciative, respectful, a passionate learner, a great student. and a very shy, compassionate girl. Now, I'm very irritable, disrespectful, don't enjoy anything anymore (not even past passions--btw, don't feel sad but could be a sign of depression) and I'm more confident.

Any thoughts of what this could be? It's not puberty (I'm 18) and not menopause(18 again). Also, no birth control or any other drugs.
