How to overcome Spongiotic dermatitis on vulva lasting 4+ months?

I’ve been having nonstop uncomfy feeling down there. I had a biopsy done and it came back with spongiotic dermatitis. The doctor told me to just use aquaphor and do sitz baths. I’ve done that daily and see no relief. This is ruining my life and all I can fixate on bc I am constantly so uncomfortable. I have a burning feeling nonstop. I now spot bleed from sex. It always seems to feel like I swell on the right inner labia and feel like it’s pulling and also the inner right vaginal wall feels like something is stuck inside me. Peeing seems to irritate it when I get “wet” seems to irritate it. Anything and everything seems to irritate it. Idk if something else is also going on but I feel so hopeless. I’ve seen 2 specialists they just say “I look fine”. This is ruining my life. I am constantly on edge bc I feel like this. I got tested for BV, yeast infection and STDs and all came back negative. I hope there is hope for me. This is going on 4 months now. Has anyone had something similar? What helped you??
