For the past 4 days or so, I've been experiencing shortness of breath. Not really hyperventilating, but my breathing feels very shallow &amp; like I can't get a breath that's "deep" enough, even when I try really hard. It started out only happening in the evenings (when sitting on the couch doing nothing) but is now happening all day &amp; i woke up twice last night due to difficulty breathing. I had a panic attack last night for the first time in years because I was talking too fast &amp; couldn't catch my breath at all for a few minutes &amp; thought I was suffocating. I've tried many breathing techniques &amp; none seem to help.

The thing is, I've dealt with severe anxiety &amp; OCD for over ten years &amp; I have NEVER experienced this before. Everyone keeps insisting that it must be anxiety related, but I have actually been doing very well with my anxiety lately &amp; I am at a pretty calm/content state most of the time. 

I received a negative COVID test a few days ago, my blood pressure is really good, my pulse rate is normal, &amp; otherwise I feel fine (aside from dizziness &amp; feeling lightheaded as a result of the breathing problems). Is it normal for this to just randomly happen with anxiety disorders? 

And yes, i will be booking an appointment with my doctor today. Just wanted to see if others have experienced this.
