I just had really bad trouble breathing?

[AllieSheaamt]

I was fine all day, but i was just lying on the couch on the phone and i felt like i couldnt breathe that well, so i hung up the phone with my boyfriend and i rushed upstairs in a panic, telling my nan i had shortness of breath .. and then as i started to panic i started to shake and it was so hard to catch my breath .. :S now im not feeling so bad, but everyone in my house smokes around me, and i have anxiety, AND i used to have asthma but i dont anymore, i dont think. And also, earlier, i was cleaning the bathroom with this cleaner and i got some on my hand, and i bit my nail...so i dont know if that could be any of the reason. I have a huge fear that i might have to go to the hospital and get hooked up to some kind of oxygen tank or something, and it scares me and makes me panic more...im so nervous, im afraid im gonna get worse after i get off the computer , because entertainment makes me forget about breathing. Im going to the doctor tomorrow but does anyone know what could be causing this? i need some comforting adivce...and its pretty late too. Thanks everyone i appreciate it ever so much. Im 15 by the way, and i dont smoke.
