My labia/vagina is burning???

So, the entrance to my vagina and the surrounding skin is burning like someone rubbed me raw with sandpaper??? I don't have any discharge but there is a funky smell. Neither my partner or I have herpes of any kind and I don't have health insurance so I can't go to the doctor to check it out. :( I did some googling and the results were like.... Shingles? And a yeast infection? And BV? I'm really confused and I think it's worth mentioning that I have really severe health anxiety so I'm getting sort of panicky :/
