Yeah, so i think I'm dying. I need menstrual cramps help, Ladies! Please?

Heat, bananas, relaxation, Advil, ha! That stuff doesn't work for my cramps. The pain is EVERWHERE (legs, back, stomach, headaches). It's so bad I've contemplated suicide (seriously). My friends think I'm joking and my dad doesn't understand that I'm serious about wanting to see a doctor. He tells me to stop whining. So, ladies, help me out here! I need all the advice and loopholes I could get! I can't afford to miss school for this crap anymore! Vitamins, diets, anything! Just please help me make it go away
