No never told anyone IRL, it's way too risky and dangerous. CTB'ing itself is already arduous as it takes research, knowledge, planning, and what not just to obtain the method, then waiting for the right conditions and time to ctb, as well as building the courage to overcome that big (psychological) elephant in the room called the SI (survival instinct).
It's also really difficult to maintain a normal front (or as close to normal as possible) IRL while being true to ourselves here as it takes a lot of energy to do so. While I'm not imminently going to ctb, I'm just obtaining my method so that I can check out when things get too shitty to bear.
