Shortness of breath 24/7 is ruining my life

Basically, for the last MONTH I have had shortness of breath all day long. It’s air hunger, I sigh every minute or so the whole day, I get out of breath when talking, walking, laying down etc.

There are a few instances when I seem to not have this shortness of breath and interestingly enough, these are the only T imes that I feel hunger. I assume it’s because I finally relax.

I have had heart check up 6 months ago when I first started having this symptom occasionally and everything was good. I don’t feel anxious about something except this damn shortness of breath and constant sighing and yawning. I even have it when talking to people, like it has become a habit. Anyone experience with this?
