I don't see purpose in disclosing it to the people that surround me right now because they are all "normal" people and I don't think they can help. My experience is that only someone that has experimented mental struggles or some kind of trauma can understand.
This was very much my view. My family are suffering themselves and I've never gotten better from talking about my issues to people. My mother knows I'm very unhappy because of mental health, but she is sick and disabled, I have already worked through therapeutic techniques and it didn't work, some mild encouragement from family isn't useful. Nobody is functional enough to handhold me in to a functioning life. I saw it as just increasing emotional pain for people with no solution, and my mother is sick and she would probably blame herself since she relies on me to help her.
Sadly I got caught up in the Kenneth Law thing so I was out with my mother when multiple police officers turned up trying to find me, and more officers went to my house where my brothers let them in to take the sodium nitrite. That kind of forced my hand, I didn't tell my family more than basics, and nothing much changed. I still don't talk about it, we haven't talked about it in a long time, because it didn't change anything.
It was revealed how suicidal I was and nothing happened, the police left and the mental health crisis team never contacted me like they were supposed to. It was awkward for a while, my mother already told me she loved me no matter what before it happened, my mother still checks my post. In the end I was probably right. Me being revealed just increased the emotional unpleasantness I think.
