My Daughter Just Informed Me That She Had An Irregular

My daughter just informed me that she had an irregular PAP result, has HPV, and now a yeast infection as well. She's 22 and living at home, so too old to tell what to do, but young enough to need some help. Is there anything I can do for her? Encouragement, diet changes, etc? Or perhaps things I should suggest she ask her doctor? Perhaps info we can read to cut through the unknowns?
