Asthma from hell ! Help please!?

Ive been using a primatene mist inhaler like almost 9 times a day, today and yesterday. I guess i shouldnt be using that inhaler but i have no insurance or Doctor to prescribed me anything. For the past few months ive been working with a carpenter in his shop and I am always surrounded and breathing in wood shavings and wood dust plus sometimes other chemicals that might be in the air such as polyurethane. I wonder how bad is all that for someone with asthma? For awhile ive been fine , working with him and nothing i feel fine but this past week i have real bad asthma and im thinking i should quit soon because its probably making my asthma real bad. But it could also be the weather i think or the season, winter time i usually get asthmatic then the rest of the year im pretty clear. I guess im just trying to know if the wood dust is not a big deal ill get over it or if its a big deal cuz i have asthma? Also if i should see the doctor or just ride it out to see if i get better cuz the past 2 days ive been wheezing and labored breathing all day and the primatene mist helps a little but ive been using it like 9 times a day! i feel like i could have an asthma attack soon, i hope not. Any words of wisdom or help please! Thank you.
