I think about ending my life
Why do you feel you should do that?
I know my daughter will be so much happier without me
I'm sure your daughter loves you and doesn't want you to kill yourself.  You should stop talking to me and go seek some professional help if you're having thoughts like this!
I'm going to do it anyway!
You need to stop talking to me and call a hotline immediately.  You don't want to make this mistake!
