Thanks for writing this, @stellabelle. I think a lot of us here on Steem struggle with depression, and I think that that is likely indicative of intelligence, compassion, empathy, and the desire for the world to be a better place (if I may brag about us so freely).
I appreciate you writing this, and the questions you raise are poignant and profound. Hope Laura is in a peaceful place now. These things are such mysteries. Wishing you the best and sending happy, unicorn fart-imbued thoughts of positivity and love your way.
