What can I do if I'm uncomfortable about going to the doctor about my vaginal condition?

Be comfortable. Not just for this condition, but any condition, you should feel comfortable with your physician. If you do not, then it is time to find a new one. From a physicians standpoint, this is what I want of you as well. If a patient does not feel comfortable with how I am treating them, I do not want them in my practice. I want them where they feel comfortable.
