Welcome to the past 10 years of my life.
If the problem is what I think it is then yeah you're going to have to wear a mask. Don't feel bad about it sooner or later we all find a reason to wear a mask at least yours is a decent reason.
Oh also leaving won't help. Sure you won't be "in the fire" constantly but you'll have to go back to it sooner or later and the longer you're out of it the hotter it feels.
I doubt it is the problem you think it is. But uh thanks I suppose.
What you do is you go deep in the woods with one airsoft gun each with just ten pellets.
each time you get hit you make a one inch cut in your arm with a razor, who ever has the least cuts by the time its over wins. My friends and I do it all the time it's a blast.
