I have anxiety even though my body can't make its own cortisol. I have to take hydrocortisone every day. (Addison's Disease)

So it must have other causes than too much cortisol.

Interesting to think about.

I had an increased heart rate (170s resting bpm) caused by right heart strain due to some problems caused by leftover PE(it never fully went away), and when I saw on the pulse ox how fast my heart was racing it induced a panic attack.

This has happened 3 times now.
