I used to, but I don't anymore for several reasons, the main one being that no one understood and their subsequent reactions/actions were more detrimental to my mental state than if I'd simply said nothing in the first place. Once I found the forum, I now had an outlet to express myself, and so this place acts as a nice stop-gap for me when it comes to being able to let out the things I can't anywhere else.
There is a lot of messaging out there about opening up and talking to someone about how you feel, but there is very little talk about how to listen and empathize with a suicidal person, it's literally all, "How to cajole someone into therapy or hospitalisation even if they don't find either of those things beneficial". Whenever I was growing up, my family talked about suicidal people the way someone would discuss horror movies or true crime documentaries, as if suicidal people were sick and disturbed individuals.
I learned the hard way that being too honest with people would lead to them sending the police to my door, a humiliation ritual that caused multiple people to lose respect for me. My husband's family was so ashamed of me for my thought crime of being suicidal, he was so ashamed of me, the fucking neighbor was ashamed of me, and to top it all off the police and paramedics addressed me as if I was a 5 year old child who lost their senses and had no clue what they were on about, rather than a grown adult who should be spoken to as such. After I had just had an attempt, instead of support, all I got was being talked down to by my husband about how embarrassing I was for being suicidal.
People are too concerned with how they look to others, seeming like they are doing the right things that align with perceived moral values of the groups they want to fit into, than stopping to question if their actions are actually benefitting the other person's interest. From my own experience and reading so many on this site, I would say that what many of us have always needed is love, and compassion, only to be met with sterile, clinical, and fearful responses from others lacking in human touch and kindness.
