Also, people can have lapses in their mental health and then recover.
There are also most certainly lots of factors that can push people to their limits. I do note that you were not successful in committing suicide, and in the name of discussion I might ask (if it weren't inappropriate to do so) why you were not successful in committing suicide. I have done a few thought experiments about suicide and it seems that some methods routinely fail while others never do.
Thanks for sharing your story, and I apologize if my comment came off as insensitive or as an attempt to washy my hands of the key issues. I'm strongly opposed to the kind of stuff that was being done to Aaron fwiw.
