I can't figure out at all what I could actually put in a note that would do anything. It all feels blinded by the fact that I'm using it to inappropriately relieve the guilt. Framing it as a completely internal issue everybody would have been helpless to prevent is a completely impossible task. Because no matter the case, its never the absolute truth, and a known lie feels comfortable in a completely different, worse type of way.
I think all you can do is leave words or something they would appreciate as individuals as a goodbye, that you were really thinking about them and everything they did for your life. It feels like the most honest way. Whatever it is will haunt them forever, done with the consideration that they don't want it, they want you. None of it should be satisfying, and none of it should leave you feeling benevolent. You can never truly predict how people will take it, consciously and subconsciously. A note can only ever make it easier in the way a pound of fat would help somebody drowning at sea, no matter how perfectly executed. Its the type of thing that seems better as a part of a story. Leaving something to forcefully enter into the narrative of a loved one's mind ought to be treated as a completely separate category of thing. Not apologizing, but authentically appreciating the seriousness that the texture your death would leave on their minds. Its so difficult I've found myself backing off of the idea of suicide for months at a time while drafting letters.
If you were hypothetically close to me for instance; I wouldn't want to know what you understand, I wouldn't want to know your worldview or feelings. I'd say that I do, and I would think that I do, but I wouldn't. I would want to save you. I would want to solve you and regret what I didn't do, and I will torture myself with your death forever. There is no such thing as a proper goodbye, and the preventable bitterness left by me that was preventable on your end would be eclipsed so greatly by my memory of your essence that I wouldn't have any meaningful thoughts or actions related to it. I don't think a letter could ever reach me, and I have friends that express the same sentiment. One of which actually told me he would not read my letter.
I am going to keep it authentic, personal, and in tune, I suppose. There is no proper attitude to address this with. Just a goodbye of the most horrifying and uninspiring nature between selfish creatures.
