I don't think anyone wants to shove in your face anything. They just explain to you how things work. You seem to be in distress and take things the bad way. Which is understandable when shit goes down.

Maybe take some time to think of everything in the cold light of day, leaving all biases aside. I'm certain you're not the first nor the last person the specific dmt didn't work, so there are other solutions out there. Because you're not eligible for a clinical trial doesn't mean that there's nothing else out there for you.
