I'm going to push my depressed friend away
Why would you push them away when they really need you?
Because he keeps bringing up his problems all of the time. I'm sick of him. His depression is bringing me down.
You should be there for your friend. They are depressed and need your help. Don't abandon them.
I don't believe in depression.
Well, it is a real thing. I think that it is not okay for you to abandon your friends when they are going through depression.
