I am all for ritually... respectfully... with greatest education, safety measures, and preparation... (this includes mental wellness of the person approaching the sacrament) working with Ayahuasca to heal depression. It wasn't until I began ritual work with Ayahuasca (and an honorable mention of the rare mushroom) that I have, for the first time in my life, experienced TOTAL and LASTING freedom from suicidal thoughts, and a generally self-destructive paradigm.
So, I have to vouch very openly for the medicine; but, I also have to place a strong disclaimer of RESPECT, INTENTION, and PREPARATION. The guidance is very clear: are you prepared to be held accountable for your entire life with such clarity?

That being said, there was one thing I realized after beginning work with Aya, about the nature of suicidal thoughts. I never actually, in my heart, meant to kill myself: it was my mind's way of SCREAMING and GRASPING for change that was absolutely critical to its stability. Death, a la tarot, only symbolizes change; and intensely suicidal feelings are symptomatic of the mind's deep need for an important change critical to maintaining its balance.
Therefore, OP, I would ask, are there things in your life that you need to desperately change? Are you holding onto, metaphorically, dead things that are best addressed, honored, and buried respectfully?
Dealing a lot with suicide, the impulse is essentially a failure of coping mechanisms. Don't end your life, life is beautiful: CHANGE it! (And grow... reach for the sun!)
Anyway, this is just my ramble, about how I would consider trying to integrate the journey, through my lens of experience. Death is change, and a suicidal impulse is a VERY intense cry for immediate change. Is there something in the subconscious that needs to be addressed?
Love and best wishes.
The other lens I would recommend for viewing, is love.

Sending loving thoughts to places of extreme mental desperation, or to places where you, as a 4-D being existing like a worm through time never received them, can be powerful, too... compassion...
Some things will come easy, some will be a test
