I Get Very Short Of Breath Sometimes, Even When I’m

I get very short of breath sometimes, even when i’m just sitting down. It happens almost everyday, and I have to take very deep breaths just to get the air that I need. It’s been happening for about a year, and it’s gotten worse in the past weeks. I don’t want to see a doctor if nothing is wrong, but does it sound like I have asthma or anything like that?
