miserable vulva

Hello. I'm pretty much just writing to vent as I have a very personal, embarassing problem with my vulva. I've pretty much lost hope that doctors can help me and I'm frustrated and don't have anyone else to tell besides my mom.
In the summer of 2008 I began developing itching on my vagina and vulva, and didn't have it treated right away because I was suffering from severe depression. I finally made it to the doctor, had a pap, and she gave me some cream for a yeast infection. The itching never went away but it got better and then would return.
It steadily got worse and in early 2009 it slowly became worse and worse. I felt like I had something crawling under my skin! I shaved all my pubes and it was examined, and nothing! I also have a gastroenterology problem and doctors simply associated the lower abdominal pain and itching with ovarian issues and focused mainly on my internal organs which turned out to be OK, thank God.
The problem continued and I went and got tested for STD's and turned out to be negative as well. Sadly, I asked to be blood tested for herpes and came out positive which brought on another load of suffering and humilation from my vulva.
I have never had any blister or sores just itching with no visible abnormalities.
The doctor said the itch had nothing to do with it, so the two are not connected. She diagnosed me with gardenella and put me on Antibiotics which did help with some of the itching. By this point all the yeast infection creams left my urethra raw and peeing burnt so bad I'd had tears in my eyes. I was taking Antibiotics for gardenella and urinary tract infection which left me in a daze for about a week. She finally said I needed to see a psychologist so I switched gynos because I was fed up.
My new gyno said everything appeared fine. She took tests, they did a complete bloodwork and everything came out fine. Nothing worked, I was on steroid medication which was only a temporary fix.
She finally did a biopsy on my vulva which hurt so bad I couldn't sit! It turned out I had lichen simplex and I was referred to a dermatologist. He did tests also and put me on a lotion for itching which helps a little.
I still have yeast infections and have all but eliminated Sugar from my diet, and it's still there itching every damn day.
Oh, and I was re-tested for herpes and HIV again and came out negative. I don't believe doctors have any clue what they're freaking doing! What am I supposed to do now!?
I don't know what to do. I have become very bitter and withdrawn, and an angry person. I don't even care for finding a partner because I am too ashamed of this. I've tried having faith that a higher power might help me. I've really worked very hard to change my thinking, I live a healthier lifestyle, be a good person, and overall try to have hope- even though all this brought on a complete crisis of faith in me.
It's really frustrating, for example, to be talking to someone out in public and to be itching or feel a sting on my labia or clitoris or any other random spot on my vulva. It makes me cry because I don't want to deal with this forever! This is so frustrating and I don't want to put steroid lotion on it, I want a solution! I don't know what to do and this is really bad! I wouldn't wish this on my worst enemy and I don't know why more than two years later I'm still suffering with this! WHY IS THIS HAPPENING TO ME!!!? Tweet
