for me it was impulsive both times, had been suicidal since about 18, and 2-3 years ago attempted but that wasnt planned and with medicine that did not kill, I had no idea about how to kill myself back then but felt as much pain as some months ago and whole last year, anyways my thing is I dont like to plan too much because it gets the anxiety to go way up, I plan but a bit like buy the things to have just in case and I wrote suicide note and stuff like that, then when im impulsive and cant take it anymore I get this motivation in my mind to "lets try if this will work this time" like SN as example my next thing, last thing was Amitriptyline.
