I have lost all hope
I am sad to hear you say this. Was there some point where that happened?
I had lots of hope in the past, but it all disappeared.
I'm sorry that you're feeling so down.  Have you thought about seeking some help for your depression?  I think it might be good for you  to talk to someone.
I told you already. I have lost all hope.
When people feel they are out of hope it is good to seek help from someone that can help you regain some control.
