I Am A Music/ Voice Teacher. I've Never Had A

I am a music/ voice teacher. I've never had a yeast infection in my throat. I'm hoarse and concerned about when I'll get my voice back. I'm home resting because I feel weak.. I'm coughing up stuff still like some phlegm . I'm 58 and work in a portable where there is possible black mold . It was found in another teachers portable close to mine. She was told not to say anything!
I don't know what to think, but I've been sick since I've been out here in this portable and have had to be on antibiotics every year. I couldn't get rid of strep last year! What do I need to do to get my voice back? I'm so frustrated. YYYY@YYYY
