What Is The Remedy For Vaginal Itching?

My vagina is EXTREMELY itchy. I think it may be due to dryness.. But nothing has been able to help me at all. There is no odor, and instead of the white goo I get when I'm turned on, I get what looks like small pieces of curdled milk. Nothing is helping, and I am absolutely miserable. For the past 2 nights, I haven't been able to sleep. I'm terrified that I may have vulvodynia.. After some research, I tried teatree oil, but it seems to have made it worse. Please help me, I'm about ready to die.
