Heal Damaged Voice
I know this is really long but please read, I really need some advice
I've been singing for about 3-4 years. When I started out, I went about it completely wrong and yelled to hit high notes, tried to do compression/distortion techniques, all the bad stuff you can imagine. After a while, it became comfortable for me to rasp and yell, and I carried on with it for almost a year and a half without any issues. My voice did get a little tired, but I would just limit my voice use and drink water and I'd be fine the next morning. I then took up smoking in astounding frequency, smoking around 3-4 times daily. Just before my smoking went through the roof (so when I was doing it occasionally) I noticed some swelling in what I believe to be my epiglottis. I had also just started an Adderall prescription, which really dried my throat. With these factors at work, my voice was really shot pretty much all the time, so I quit the adderall and it got a little better. That year I joined my school choir, and my teacher took me under her wing and I learned how to sing much more correctly, and how to warm up. After about 2 years with her as my teacher, I was pretty good. My voice still had a shotness to it, but I could sing through it. I did still stain alot when singing out at coffee houses and such. So now in in my freshman year, and I still smoke, but I'm learning how to use better technique, but my voice is just not cooperating at all. It's kinda airy and sore alot, and my stamina is non-existant. So after that storybook, my question is this: Do you think my voice is permanently damaged; and if not, where should I begin fixing it?
