Yeah, I ended up abandoning veganism, because I no longer felt (and feel) the empathy that I did back in the day (if there's much left). Being able to experience the world through the lenses of someone with low empathy makes you a little sympathetic (heh) to those that are born like that. Basically my decisions are purely rational as of today. I'm lucky to not be impulsive at all; if I were, I would have fewer friends than I do.

I briefly answered the dietary changes in another comment.
