Is it pneumonia? Is the problem here?

My chest wall is very thin I can feel my ribs. Sometimes I feel pain around that area​ and cough out blood and yellowish mucous when I have flu. It's been going on for 2 years now. Other symptoms I have are ; cold intolerance, constant fatigue, weight loss, dry and thin skin, visible veins, headaches​, diarrhea, very red and protruding eyes especially at nights​. I lack stamina and strength, my hands shake involuntarily, hypersensitive to cold. I feel cold inside my hip bones,i easily contact flu. I have 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. Please what is the problem here? Is it possible i have pneumonia or I'm suffering from low immune system. Please advise me properly
