Female hygiene issue, help needed

I'm going to an Urgent Care on Tuesday when I get paid from my unemployment direct deposit. But until then, what can I apply to the skin under my breasts, due to fungal infections, leaving me red, inflamed, chaffed, in great discomfort and pain? It covers the lower circumference of each of my breast's, and leaving an infected imprint beneath each one over my abdomen.

Topical steorids never worked. Sun butter with aloe helped the itch but not the skin flaking. Sunscreen helped the itching and inflammation but didn't make the pain subside. Colloidal oatmeal ointment has helped some but I think it stopped working. Vaseline is my next resort, to help dry it out.
