Have you considered setting an intention before salvia or DMT to ask for healing specifically for the issues that ail you? This is primarily how I use psychedelics and it works wonderfully for me, especially DMT. Sit before you partake and just feel your heart as much as possible. Just place your awareness in it... feel the thumping, try to imagine being inside of it. Maybe pull your breath into it if you feel like thats cool.
Then simply state your intention. Your higher mind (call it whatever you want but the "bigger you"

will take on the intention and try to assist you. It's not always what you might expect and sometimes it takes a few sessions before everything gets cleared out. Sometimes they'll tell me a story to help heal or they'll focus on a pain in the body until it clears.
Anyway, just figured I'd suggest it since it's the way I experience this beautiful molecule and I've made leaps and bounds in my own personal growth. I've been there, I feel for you. We get it.
Weaving the words of the Universe, dancing to the song of our souls. Love is my only weapon. Knowledge is the empty vessel I pour from. Thank you for being here at this time, beautiful soul.
