I can’t seem to find the choice now, but I’m pretty sure my stats were a mix of numbness and self-harming choices. And personality-wise: not trusting anyone, not thinking of myself as a person, etc.
At the beginning, I also told the Ancient One that I wasn’t sure if I wanted to live, and he told me to choose to live and, if I regretted it later, I could always do something about it. Which, apparently, I did xD
