I've never been diagnosed with anxiety but might go see a doctor soon about it. Basically, I sometimes have a lot of trouble breathing. It feels like there's a weight on my chest and whenever I try to take deep breaths in, they never feel like enough, as in I never feel like they bring enough oxygen into my lungs. Sometimes yawning or sneezing helps "deblock" this little issue for a few breaths, but then it just comes back. It's really affecting me. I've tried taking magnesium glycinate pills but they haven't helped that much.

Am I experiencing anxiety?
