asthma is what is sounds like to me.. But you should go to the doctors, ANd don't be afaird to go to the Doctor, if it is anything serious you would want to know early.. But I don't think it is.. GO!

That's no small thing and you should get it checked out immediately. It could be other things causing the breathing problems if you work in a garage where you're breathing exhaust, carbon monoxide, gasoline, etc.

Please get over your fear and get it checked out and it possibly can be fixed without long-term care. You know that miners underground breathe in coal biproducts causing black lung, but they generally have to be exposed to it over many years. Since you're only 16, the chances are good that your symptoms may be treatable.
