Actually did a DIY psychotherapy and it worked.
Without needing to buy illicit (or at least heavily regulated) substances that induces high or alter states of consciousness.
And actually know what I'm doing to myself.
Most people don't. Most people can't.
Even some psychologists struggles with it and it's not even a practice towards themselves.
I have a more direct access to my subconscious. And inner child.
And consciously gained a 'conscience'; the real one closer to the higher self, not the guilt and shame inducing kind.
Got induced with anxiety by watching something horrific...
All that hypervigilance, intrusive thoughts, disruptive sleep, startle reflexes, actually worrying thoughts, etc...
And solved it within 3 days. Yes, I can consciously solve long-dragging anxiety, and know what to do if it ever happens again.
Playing therapist to a psychologist/counselor/therapist.
Without even being a psych major myself.
Jumped while spinning over this particular body of water within a cave;

Drank an entire 20% or so alcohol (Soju) bottle (about 360ml) as someone who doesn't drink regularly. Did it for the money.
I'm only 5'4 ft and less than 50kg skinny and out drank everyone who isn't a heavier than average regular drinker...
... I'm a novice drinker who prefers vodka and tequila over beer and wine for some reason.
And since I only drink, like, practically 2 times a year at most; I'm sure my tolerance level is more or less the same whenever I had to drink.
