I think it's rational to worry-
I'm just not sure how much good it does you to concern yourself overly with it.
There are ways you can leave a positive memory of yourself for those left behind-
Ultimately though, i know in my case specifically it's a lost cause to worry since i can't affect how others think and feel once i have CTB.
If others want to be angry or think badly of me for it then that says more about them than it does about me- i will leave an explanatory letter, and a detailed will- and i will try to do my best in both to address all possible issues that could arise following my suicide.
It matters more what i do now, while i'm alive- that will be what affects others' points of view about me when i'm gone.
That is my belief... does that make sense? So i try to be a good person by others now. Sadly all i do is screw up...
