Fungal pneumonia. Me on what to do!

I may be suffering from severe fungi infection. One of the signs​ I have is dryness and irritation in my inner thigh. My scrotum is always itchy. Someone suggested It might be Jock itch which is a yeast infection. I've had this condition for years now and I've often overlooked it. 2 years​ ago I started having other complications such as cold intolerance, dryness of skin( which I assume is due to lack of oxygen), pain around my ribs, fatigue, weight loss and exhaustion, constant headache, red eyes especially at nights​, blue lips and skin. I can't withstand cold or fan, I can hardly concentrate, diarrhea, shaking chills. I ran a few test such as urinalysis, widal test, glucose, HIV, chemical pathology, thyroid function test, complete blood count CBC, Liver, all these test showed am healthy​. One particular sign​ is yellowish mucus and sometimes bloody​ mucus when I have flu and rashes around my ears. It also seems like my immune system is really down. Kindly advice me on what to do
