Earlier on, I had severe heartburn which I believe was caused by drinking strong coffee on an empty stomach. Then I started getting a weird feeling in my back and my arm and then immediately thought I was going to have a heart attack as I suffer from health anxiety. I had to sit down at work and began to hyperventilate. Usually when I feel a panic attack coming on I pace up and down rather than sit and calm down. My oxygen levels was 90% at this point, heart rate was 160BPM, sweating profusely and then I told myself I have to sit and calm the fuck down before I end up in hospital which I want to avoid so I sat and started to breathe slowly, ignoring the pain I was having in my upper back and stretching to relieve it somewhat.
My oxygen has gone back up to 99% and heart rate down to 60bpm but last time this happened, I was so scared I was going to die. I'm sorry I'm posting here, I just need to let it out. I honestly was scared and glad I managed to calm down. I had to go and lay down because I was dizzy and felt a bit off.
