This morning I spat blood into the sink and have been tasting it all day. I also feel like I've been punched in the gut and have had a cough. Could this be because of bronchitis? I was recently in a big house fire and inhaled a crapload of smoke trying to put it out. I'm hoping it's something fatal, but I doubt that's the case.

I think you should go to a doctor to find out forsure what is going on.
