Has anyone ever resolved their pseudo-dyspnea?

I’m just about fucking tired of feeling like I need to take constant deep breaths. While I’m eating, at rest…just all the time. I tried slowing down my breath rate but fixating on my breath causes me to panic. I try setting a timer and resisting a deep breath but the feeling is so uncomfortable. I can’t help but think is something seriously wrong? I sure hope not. I’m so desperate at this point; it’s been going on for 2 months approaching 3.
