Very much afraid

I am suffering from Tuberculosis from last 2 years. I consulted a doctor and when I gone through a sputum test, it was positive So he gave me Akurit-4 tab along with some other tablets too. Which I taken for about 2 months, but problem increased. I consulted other doctor, and he changed my medicins but some much stronger specific of TB. Yet I was not getting benefitted properly. Then I consulted one of the retired doctor very senior doctor and he said to take my chest CT and X-Ray to him. From those two also TB was confirmed. So He suggested me Strptomycine Injection for three months alongwith some other TB related Tablet medications. He called me after every 15 days and his fees was also too much for 15 days as he was retired and every after a month, he asked for Chest CT which is also very costly. So I continue to take injections and tablets. After three months I was very much about 100% satisfied and I stopped to go to the Doctor as he again ask for CT. but after 20-25 days I stopeed my medication, I again felt breathing problem after a 15-20 minute speaking as I am a University Lecturer. I again consulted the same doctor. He scolded me again and said dont stop the medications until I told to do so and he again ask for Chest CT and called me after 15 days. I again started to take the same medicins for next 1.5 months and got again 100% relax and again stopped them before 20-25 days. But now again I am geeting same breathing problem as well as some congestion in my neck which remain still from the starting of my TB. Doctor says this congestion is not due to TB. Its due to allergy. I dont want to go to that doctor when It is clear that I am suffering from TB, why I would go to such costly doctor and each time I take new Chest CT. But again and agin I am with breathing problem lets me think that "Is now this problem is a lifetime problem and I have to live with it or there is any easy solution? Will I be a normal person or not and going to die very soon?"
Please any doctor here can suggest me what I DO?
