I really wouldn't blindly recommend Psilocybin to people. I got the idea of trying to fix my health anxiety with it from HN about a year ago. Took half a dose, had a pretty good time for around 2 hours and then the worst panic-attack meltdown of my entire life. I started sweating all over, dripping sweat from my head, being 100% sure that I'm going to die - in the end ambulance fixed me up with an IV.

My anxiety disorder only got worse since then. Every time I see an ambulance I still get flashbacks and instant anxiety.

The drug isn’t gonna fix you by itself. It facilitates a state where you can fix your brain. I’m sorry you had a bad experience. Perhaps it is worth trying again in the company of a guide or others. It’s also worth preparing for your trip by determining what kinds of things you want to try and accomplish while you’re on it.

Psilocybin is a powerful tool but it seems counter to the adage of "set and setting" to use it when beset by anxiety. As a prophylactic for it is of course a different story.
