To add more to what I've mentioned above, I still deal with moments in trips or whole journeys where I am battling depressive thoughts, thinking, and states. And the degree of intensification tends to be overwhelming when occurring. But I have a different vantage point from which I can interact with these instances, and this vantage point comes with a kind of power. I try to use this power to help myself grow and better manage what I deal with it [effect of depression] and instances of intrusive thought penetrating my thinking. However, sometimes I fall down and it takes a while to get back up. It's the nature of the game and comes with the territory. All that said, I don't think that all people with depression should do psychedelics on their own without some kind of facilitation.
I also have to agree with what Tomtegubbe mentioned above about being strong willed and the reasons why. While I deal with depression on a regular basis and as a result don't necessarily feel or realize that strong-willed, I'm still aware that I am based on always fighting the good fight with my experience with depression. Psychedelics are my swords and shields, but weapons can be wielded against one when not prepared.
One love
