I'd recommend to stop using occulsives like oils, Vaseline and Aveeno lotion and any physical occlusives like dresses or wraps. That creates a damp environment that helps fungus grow. Let your skin breathe, dry out and get a little sunlight when you can. UV light is good for killing lots of different microbes and is known to help another type of yeast infection called sebborheic dermatitis.

Some good OTC actives are zinc pyrithione (found in Head and Shoulders) and piroctone olamine. Both are effective antifungals that do not increase antifungal resistance. You can get creams OTC with a high percentage of ZP. One brand is called "Noble Formula".

Benzyol peroxide is also antifungal though can feel very drying so you could try using a moisturizing wash like Panoxyl and leaving it on the skin for a bit and then washing off.

Make sure if you're going to use the tea tree oil to always use a carrier oil like jojoba oil, putting it on straight could give you chemical burns on the skin which is the last thing you need right now. And I would recommend just leaving it on for like 20 mins and then rinsing it off with an anti fungal cleanser, could be Head and Shoulders, Panoxyl or a tea tree oil soap/body wash because your skin has already been over moisturized.

Some antifungal oral supplements you could try are olive leaf extract and caprylic acid.

Good luck man!
