Say what you'd most like to hear...
Sometimes we just need to hear a certain phrase for us to feel comforted and happy.
Say something to yourself that you'd most like to hear right now. 

That I mean something
There is a permanent cure for mental illness. In my case, depression and anxiety.
It will all be okay eventually, these things just take time. We all know you are trying your best, so just keep on pushing and things will get better, I promise.
I'd like to hear "I love you" from someone who really means it
I want to tell myself, "Hey Rex, you're doing the best you can, and you should be proud of how far you've come. Maybe other people don't understand, but you're working really hard and you should stay hopeful."
I would like to here that u care n that u ll never leave ☹️
I'd like to hear "You're worth fighting for, you're loved and needed"
You're not crazy. You did your best and that's good enough.
You're doing your best. Sometimes there's not much you can do. Just focus on getting better and if it takes time. Then that's fine. Don't be too hard on yourself.
Whatever it takes to move forward. One step at a time. You'll get better at this. But it takes time. It just does.
You are loved. You are appreciated. You are blessed. You are great!
