How should I start off and end a speech about teenage suicide?

Within the speech I will be speaking about suicide rates, suicidal behavior, common ways of suicide, and how suicidal people can get help. So yeah, does anyone have any ideas to how I can start off and end a speech about teenage suicide?
Your help is appreciated thanks.

I THINK IT WOULD BE REALLY COOL IF YOU JUST STARTED OFF BY SAYING RANDOM STATISTICS ABOUT suicide. Something like (don’t mind the statistics i made them up) this look around the room, 44% OF ATHLETES WILL/HAVE COMMITED SUICIDE, 12% of students attending private school have/will commit suicide,10% of students commiting suicide weren’t on drugs 15% of students living in normal middle class households will/have commit suicide, 30% of teens who have/will commit suicide have totally oblivious friends, 20% of students who commit suicide had shocked teachers and parents, 70% of people who knew students who commit suicide had no idea it was coming. Now look around the room, do these people seem happy, think about it. (then talk about like how you can help this stop) GOOD LUCK!!!!
