### input:
I am a healthy 110 lb 19 year old female. I have had this shortness of breath since I was about 11 years old. I get it at random times throughout the entire day. I have had an inhaler since about 12 years old, because the doctor said i had asthma, but the inhaler never really worked for me. I went to the doctor about 3 months ago and he said it was anxiety/panic attacks. I know it cant be a panic attack, because I dont get  any other symptoms of anxiety, besides for beign paranoid when i get the shortness of breathe. It feels like I cant ever get a full breath. Another thing you might need to know, I was born premature at 5 lbs. I was on a breathing monitor for a few months after birth, because Id stop breathing in the middle of the night. Ive had breathing issues my whole life. Please help me figure out what this can be.

### output:

Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you should first get done PFT (Pulmonary Function Test) to rule out lung diseases. If PFT is normal then no need to worry about asthma or other lung problems. Stress, anxiety and panic disorder can cause isolated breathing difficulty without other symptoms. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor. Don't worry, you will be alright with all these. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
