Yes. I first failed when I was fifteen. My memory of the incident is very hazy as I repressed it and was only capable of reconstructing it after I was told about it, years later.
For some reason or another I was going to do it that night. My parents were rarely asleep until very late in the night and I was frequently in trouble for staying up, so I waited for them to fall asleep while browsing the internet. My best friend came online at around 2 AM. I messaged him for one last chat.
I don't really know how it happened or what order the conversation happened in, but he said he had to tell me something and that he wasn't going to talk to me any more. I forget if he indicated why but it ended up having something to do with new people he met. I was very distraught at the idea he was going to abandon me and I explained what was going to happen. His reaction was to encourage me to do it, and he reasoned that 'if I was going to die, I could [tell him what was at the time my greatest secret, and very revealing]'. So I told him and he went offline.
I failed due to choosing a very poor method. I completely forgot this happened and befriended him again at some point. I remembered everything about the night but his involvement, and had forgotten a lot of things related to him in a similar surgical way. I mentioned later on he didn't know the secret thing and he confessed that he did. Between his explanation and my own memory/recordings I was able to verify it. It did mess with my head.
I firmly believe there is a difference between accepting someone's decision to find peace out of love - supporting them regardless of what they do - and callously encouraging a suicidal person to go ahead. The latter may push an impulsive or undecided person over the edge and is hurtful even to the rationally suicidal, as it comes more of rejection and indifference than care.
Sometimes people may push you away aggressively if they think they can't stop you from suicide or want to call your bluff as well. I also think this is generally very harmful but it is not motivated by apathy in the same way and tends to be regretted.
Your decision must always be your own and no one else's, insofar as that is possible.
