That is very natural human thing to fear.
We all feel that on some level, be it in the forefront or back of someones’ mind.
IMHO that is why it so important when working with such substances to do so in the safest way possible outwardly, with someone you trust by your side.
It’s the inward letting go that some people have a really hard time with as your sense of “self” starts to disappear...all the while your brain feels like it’s being defragmented and tapping into the deeper meanings of things simultaneously as you disintegrate.
That could be uncomfortable for some...and personally it was a combination of faith that it would help me and being at the point where I was also considering electroshock treatment - this being the lesser of the two evils it seemed hahaha, that pushed me over the line.
In several US states they have ballot initiatives to legalize mushrooms and the FDA is doing trials to knock it down from being a schedule one drug
(meaning no medicinal value and highly addictive) - which it is almost the complete opposite of.
The big spender Compass Pathways wants exclusive therapy rights as repayment for funding the FDA trials.
So once again...a legitimately helpful drug, already highly stigmatized, will be inaccessible for those who are not able to pay for such services out of pocket.
Even if insurance eventually conceded and paid a portion it would still be unaffordable with people claiming exclusivity rights to something that you can go pick in the forest almost year round.
Anyway...yes, it can be fear inducing, that is why I suggest people educate themselves as much as possible and work with someone experienced as well as practice meditation if you are going to be using to help with depression or especially anxiety.
All those things can help put you in a “safe” place...but (depending on how much you take) can be very uncomfortable for some and difficult to just let go and be with it.
