ok its been almost three months and i still have trouble breathing. Its not getting worse,but its not getting better. i have visited tthree diff. doctors and they said im fine. it seems worse at some times and better at others. i know its not asthma cause my doc. said and i never have any trouble walking or running or excersising. My mom refuses not to bring me to another doctor cause she says its in my head or a panic attack and its a waist of time. wat could this be?

My mom also watches me sleep and says i have no problems sleeping.
