I'm a fifteen year old girl and exactly a week before I start my period I start feeling very lightened an dizzy randomly. Through the next week I'll go through spells of nausea, lightheadedness, and just not good in general. Emotionally I'm mostly depressed and I can hardly get out of bed. I'm very anti social during this time and when I am around people I tend to get extremely irritated over the littlest things. My mother has issues with her PMS to the point where she can hardly function without birth control and mood stabilizers. The first three years I've had my period were easy but the past two years have been rough with my periods never being on time and my PMS absolutely horrible. I'm wondering if what I'm feeling Is something normal and if I should suffer through or have my mom take me to the doctor.
