Can I end it all?
Why do you want to end it all? Can anything be done to help you overcome this issue?
No I want to end it all, I'm tired of my life.
If you feel like you don't want to go on living, you can get immediate help.  I can transfer you to a hotline that can listen to your concerns, and try to give you the help you need.
What's the point of doing that? It won't help. I wasn't diagnosed with depression anyway.
You need to get help if you are no longer interested in continuing life. Think of those that love you and need you.
