I am 21 years old, I have never had sex, and I have missed my period for 3 months in a row. I live a high stress life (I am a college student), my diet prior to this month has been poor (Usually 1-2 meals, mostly junk food), I get no exercise what so ever (I am very sedimentary and do most of my work sitting or lying down), I have a high caffeine intake (3 cups of coffee a day, sometimes energy drinks as well). I don't have any irregular pain in my body, so I don't think it's a cyst. Sometimes my breasts are sensitive though, and I have (for a while) had strangely excess hair growth on my chest, chin, side burns, and upperlip. Does anyone know what might be wrong with me or have/had similar issues? I have asked a few family members and they stay it's likely stress and my dietary habits, but I'm worried and feel rather lost.
