I an a 14 year old girl. I'm about 5 foot and weight a little over 100 lbs. I have a history of asthma and had a ling close as a girl and had to go the hospital. I have been having trouble breathing all weak and it has been very painful. My mid/upper back has been also hurting as well. I have also been feeling quite lightheaded. My friend also noticed how much my lungs expand when breathing. My parents really don't care and refuse to take me to the hospital. Please help.
