A friend told me about some place in Joburg that does ceremonies like that. You take a dose of mushrooms and they watch you.
With that being said.... bear in mind that some of the benefits of mushrooms could be likened to accelerated therapy.
Let me explain. Mushrooms don't magically fix YOU. Mushrooms give you the tools to make changes to your life faster. Mushrooms give you that deep introspective state where issues you have long buried come to the surface, and you can deal with them. Or at least, realise that you have to deal with them.
Yes, they are to an extent happy pills. Because of the effects they have on your brain, they can make you feel better. But their best and longest lasting effects come from making you see yourself differently.
So, don't think that mushrooms are a magic bullet that will make your problems go away. They might just change your perspective on your problems. They also aren't the ONLY way to make a breakthrough - you can get there by therapy and meditation.
I think mushrooms have the potential for great benefit in dealing with personal issues, or encouraging personal growth, but you have to see them for what they are - a complement to what you are doing, not a replacement.
If your therapist just talks, then find a new one. Some are better than others. A lot depends upon the bond between you and your therapist.
You also have to "take the power back". Start being in charge of your own recovery. Start reading up about things you can do. Meditation is a big help, as is understanding of mental health and your own particular situation. Doing that work will make it possible for you to integrate what you learn by doing mushrooms.
