As a cancer survivor, I can confirm the absolutely amazing, life-changing effect that psilocybin had on my depression. After cancer, it gets really difficult to "reintegrate" with society. Most conversations sound absolutely pointless, I felt like there was less grip surface between the concept of me and almost everyone. The depressions after cancer are commonplace, and mine were strong, too. The difference in depression recurrence and intensity after a single 3g dose of psilocybe cubensis was spectacular. After a couple of months I started on psilocybin micro doses and, so far, along with hormone replacement therapy (I lost a testicle to cancer), I'm finally feeling OK. Much better than OK. :D
I am not the person you replied to, however spores are readily available online in many nations (they are absent psilocybin/psilocin, and thus are often unregulated and lawfully sold as syringes or prints), and techniques like "PF Tek" are simple, well documented, and speedy.
