For my past attempts, I had written notes. Each time I failed an attempt, I'd find something dissatisfactory about the note and I'd rewrite it. Eventually, I lost interest in leaving one, since I'd never be able to properly explain myself anyways. Those close to me know I hate life and that CTB is my life goal, so it's not like they'll be left in the dark. But I feel much better now that I've ditched the idea of leaving a note. Less pressure, I guess. Besides, it gives investigators less material to pathologize me with, even though I'll be dead and it won't be any of my concern.
