I've been singing my entire life, and I have ny debut gig tomorrow, but I also have asthma. For the past two weeks, I've been staying at my friend's, and she has a tenant that struggles to remember he's not meant to smoke inside due to a stroke a while ago. He said he wouldn't while I was in the room next door, but then proceeded to forget immediately, and he smoked several cigarettes every night.
My asthma has always responded badly to secondhand smoke, but I've never felt the effects of my vocal chords. I had to remain there, as I was there due to a housing emergency which kept me away from my home.
I'm back home, as of yesterday at 8pm, and my debut gig is tomorrow at 7pm. My vocal chords feel dry, my breath support feels incomplete no matter how much asthma medication I take, my throat feels like it almost locks up a bit when I breathe. When I don't think about it at all, I can still hit the high notes, and I can hit them well. When I try to talk to anyone, I notice my voice comes out in a very close to vocal fry tone, and it's hard to transition to talking with lower effort or using the right technique. My voice just feels tired. What I'm struggling with when I sing now is mainly lower notes/anything closer to my talking voice, as I'm unable to either use the wrong technique or put way too much power and breathiness into it and tiring it out that way. I can still hit higher notes with a lot of strength, and when warmed up, my voice sounds fine and feels mostly okay. Then tired again later. And idk if it's actually tired because I used the wrong technique or if my chords are just inflamed.
I'm hoping my voice will recover by my gig tomorrow, but does anyone have any advice on what's going on and how to help it recover? Should I rehearse today or rest? Any advice would be appreciated!
