When talking about my son, I say took their life, or died by suicide. The phrase committed suicide diminishes the loss/act/cry for help by criminalizing it.
Alternately my best friend I say lost his battle with depression. I think the current internet self censored version of unalived is acceptable as well. I for sure would not be offended if someone asked if that is how my son died anyway.
ETA: any plans to make a mobile version? I am going to go dig out my iPad so I can read the list, my old eyes cannot see everything on my phone.
