I haven't got any sleep this night because I'm so worried... But if I understood corrctly, you guys are saying that I have nothing to worry about. One time doesn't kill like in most of things and what I did was over-reaction. Thanks for your comments!! Now I can relax so much after hearing that and I can try to sleep now a bit. Thank you for once more!!
Please stop worrying! It takes years (greater than 10+) of CONTINUED exposure to HIGH levels of asbestos to cause lung damage. If you and your friends were in abandoned houses, there would be a lot of regular old dust and that WOULD cause you to cough. If it has been more than a couple of days since you were in the abandoned buildings and you're still coughing, I think it's very likely being triggered by anxiety. If you have an underlying issue like asthma, that could also be causing the cough.......but my gut is telling me it's anxiety. If you are STILL coughing a week from now or develop a fever or any other symptoms, see your doctor immediately. Otherwise, drink lots of water and just try and relax about this asbestos scare. The amount of time you were in those buildings could NOT possibly have exposed you to enough asbestos.
You'll be fine!
