Honestly, I feel that both lines are a little too 'anvil over the head'. Maybe you're looking for a line that has that impact, but there has to be a *slightly* more subtle way of getting the reader into the story. Both of those lines come across as very emo to me.
You could just say, "I was two years old when my mother died", or "My mother died when I was two years old", THEN talk about how it was a suicide. I don't know, I just think that sounds better. :/
