Lisinopril and sounding

I took the horrible drug for five weeks. I have been to the doctor 3 times. They gave me anti-biotics and said I had brochitis. I have a terrible sounding cough and mucus, I missed over two weeks of work and sent alot of money on medicine. I stopped taking Lisinopril 10 days ago, I feel better but not 100%. My doctor says that if will take a while for the cough to go away. I so mad because I really believed I was dying and took chest x-rays and a TB test. My boyfriend has been giving my dirty looks, and guess he think he going to catch somethimg This medicine has ruined my summer and my vacation, because I'm afraid that I will gave a coughing attack so I stay close to home or if I do go out I keep cough drops and cough syrup in my purse. I feel like a drug addict.
