I Have Been Dizzy For A Week Now And About

I have been dizzy for a week now and about two days ago my eyes starting feeling cross eyed. One of my eyes feels like it's going inward and I see double of things. It's getting worse as the dizziness is getting little better. I was nauseous the first day of the dizziness but that has subsided. I'm really concerned about this and I'd like to know what's going on. It's affecting my driving and learning because I can't see well.
