text: why can't i breathe? i have trouble breathing. i'm only 14 and i'm not overweight or anything...but when i'm breathing i have to do deep breaths all the time and then still i can't get enough air in. it's only been happening a couple of months but now it really worries me. i think you should talk to you parents about this and they may consult a doctor. if you are not smoking, not over weight, you may be asthmatic. then again i have a great grandson that is 4 months old and needs breathing treatments so, i think before it goes much longer, you need checked out. it just is not right.
