Hi! I have a problem. I used to know how to sing when I was in the 7th grade, I'm Nigerian and I was 10 then, I was in a boarding school and we drank only warm water but then I changed to a day school and started getting addicted to cold water but I'm not sure if that is responsible for my current situation. All of a sudden I couldn't sing. I didn't practice for a long time an now my singing voice is gone. I'm now, back the I could go high when it came to singing but now nothing. My voice is bad. Please????? How do I get my voice back
