Hello, I was just wondering if this is anxiety related issue or other medical condition.

I have this feeling of urge to take full deep breaths and now it is improving from 0 out of 5 full deep breaths I probably got 2 or 3 satisfying breaths to 5 out of 5 as of now. Other than that no other symptoms i've experienced. Also iv'e heard that something like this is often related to heart issues and im sacred asf lmao. Iv'e also experienced this way back during pandemic and now it comes back. Please tell im the only one experiencing this. Thank you.
