is this normal?? am I alone??

Jamie
14 days before each period, I get SUPER nauseated. And I'm terrified to throw up so I also get really anxious with bad anxiety attacks. Once I start my period and the week after my period, I feel amazing! But 2 weeks before... it's horrible. Im 21 and I don't understand why this is all of a sudden becoming an issue. 
Any suggestions on how to combat PMS nausea?? And anxiety??
