I have no advice for you to consider.
But I'll share my perspective:
Life can be worth living. It takes something to crack the pain and inspire hope. Could be anything, the puzzle is discovering what it is, and can I endure life until it comes.
Both of my parents are alive. I struggle with how my failure to cope with living and the event of my determined and premature death will affect them both. I wish them no pain, no sadness, no embarrassment, and no perpetual-wondering "what could I have done".
But, if I reach the point of no turning back, I'll leave them a letter, letting them know this is what I wanted and that it wasn't because of a mood or due to some temporary madness or depression.
Life begins. Life ends. I believe I have the right to say when that end happens. I won't bring on that end because of spite, or revenge, or any other personal feelings. It will be because I've fucking had it.
I'm still mindful of my parents and how they would carry on in my absence. I'm concerned for their wellness in the aftermath. But I'm hopeful that I will find that thing that inspires me to live on for its own sake, not because I'm concerned for my parents.
Hope this helps.
