Thank you for sharing your hearth.
I feel for your path.
Just as yoga, floating tanks, singing, ...etc..., the plants are IMHO also tools.
I suppose you know already that there is no miracle solution like instant 1, 2, 3 and hop all is over and only sunshine from here on.
I was intrigued to read you did find bliss on own legs in the middle of a crisis, and also intrigued it slipped again. Like a frequency found, and lost.
But then again it is never lost, the tune is out there and you know that.
I hear so many people having your issues, in another color or detail, but also not tuned into "life" in its best suit. It is a very human condition which has become a lucrative source for some professions. It will probably not surprise you that part of this stream also invaded the alternative sector waiting for people like you with only business in mind, pretending otherwise in a convincing professional way. Peru is heavily affected for instance. This I say not to spoil your day any further but we must be open eyed and honest.
I hope so much the plants can tool you in re-tuning the hearth and soul. I believe your biggest asset is still YOU. If you manage to reach a satisfying balance again you might become a helping beacon for others as you know the road like no other.
As mentioned: balance. That is enough IMO, the always-happy paradigm is deceit.
For me, the dark is never gone and does not have to. It's part. But how much weight it takes makes the difference. A deep experience with the plants also probably incorporates the full spectrum of possibilities, dark included. The session is succeeded IMO if all, good and bad, can be smiled too indifferently. Because then the smile originates and sources not out of the emotional territory, it has surpassed that.
The part of you accessing bliss in your text, please forgive me, still indicates emotional wear and tear, that is not a crime but still showing vulnerability, a very unstable situation, a coin on a side, and as illustrated by your further resume, ready to tip over. And it did.
Yes, the plants can bring one past the emotional wear and tear world, where the emotions are not gone but lost their canon power over you. I hope you reach that point, that is my true wish. I know it awaits you. But you'll have to give away most of your emotional addiction (for both good and bad feelings, no difference here) to reach it.
I would hope not to come across condescending, maybe my suggestions are not relevant to you, I might be wrong all along, I just express my thoughts.
