Had a 154 bpm soon as I left 82 bpm

I really hate my anxiety when I first got there I had to talk to the nurses they explained I keep getting turned away for pulse and once more I’ll have to get a note from my doctor ( which didn’t help my nerves at all) first time around I had a 154 i took the 10 minute option closed my eyes breathed through the nose then my 2nd test I got a 130. As I’m in the car on the way home I decided to test myself and I ran a 83 I really hate my anxiety guess I’ll be switching centers I don’t have a doctor or the money to get a note
