If your mother is no longer alive, how old were you when she died? How has losing your mom impacted your life?

My mother died when I was 12 and inspired by this question from @Bellatrix, and a the answer by @LuckyGuy, I am asking this. I was well into my 30’s before I met another woman who had a similar experience. Now it seems I am not the only person who lost their mom as a child and now I am wondering who else has had a similar experience and how it has impacted their lives.
