Hey all,

I'm a 16 year old female, and I've noticed recently that I've had instances when I have a very hard time getting a deep, refreshing breath or yawning. I can't get a deep breath, and it's starting to get a little scary. I'm hardly ever stressed out or anxious, and it doesn't really seem tied to anxiety. I could be wrong. It's not my heart, just my breathing, because my heart rate doesn't change at all. I've never had problems with it before. If I could get some insight that'd be great!

Thanks.
