Psychedelics & Cannabis have been great tools for my own personal coping with BPD. I never once used them to forget about it entirely, only to reflect. I've naturally been introspective for the longest time, psychedelics have only helped with resolves in my own life. If it weren't for such windows of reflection, I wouldn't be who I am today, & in many ways I've taken huge bounds in a year's time in my social life than I ever did up until those points. The credit isn't all on the tools though, it's what I've made of the oppurtunity's they can provide.
I still struggle with BPD, it was never truly dissolved, but the limitations of it have been overcome in many ways. The fungus can be a great medium to address such struggles in life.
