Whats a yeast infection?

Since you used to have a regular period and it stopped, and since you are having some sort of symptoms of something being wrong with your vagina, you should see a doctor. Foul smelling discharge is not normal. Green discharge is not normal. Itching insanely is not normal. Buring during urination is not normal. All these things are signs of a problem. A yeast infection (caused by a fungus, not a bacteria btw) won't kill you, but you would not have the same symptoms for a whole year from a yeast infection and be able to tolerate it. A vaginal infection may not kill someone, but it can affect there ability to have children, so it is important to get it checked out.
