My 20yo has unsuccessfully attempted suicide three times. My daughter has been hospitalized twice with suicidal ideation. I've attempted several times, the last time in January. My kids don't know though. They think I had a reaction to my medications and then self admitted myself to the psych hospital after a week in the ICU to deal again with my PTSD. We all have diagnosed PTSD from living in a domestic violence situation. My other son is undiagnosed and stuffs his feelings. I worry as he's been rather off and impulsive lately. My kids keep me here for now because I'm afraid if I left, they would follow.
It was the most frightening and traumatizing experience to have my son make those attempts and even to have my daughter threaten them. She planned to jump in front of a train. She lost two friends to suicide in a year, so I took her ideation and plans seriously. I imagine how much pain I cause my own 77yo mother with my actions.
I can't claim to know the pain of losing a child, but I know the daily fear that I live in knowing one of my children might try again. I know this is the fear my mom lives with about me.
I wish there was something that could erase the trauma and the scars it has left on all of us. We all do try to recover in our own ways. The memories of some things and the weight of the past just feels like too much sometimes.
I know that's not a direct answer to your question, only a somewhat related perspective.
