Hi, I'm a 22 year old female. I tend to get breathless time and again and this never used to happen before, I also used to have panic attacks out of nowhere. I have a case of claustrophobia, even in open spaces. I sometimes wonder if I am not losing my sanity, I used to be so healthy, now I have noticed that I've been losing body weight, my breathing problem usually is more pronounced when I'm travelling even over short distances, please help!
