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. 

You'll be ok. That sick feeling in the pit of your stomach will go away, you will stop having random outbursts of negative emotions and things will get better.
It's going to be okay.
Please be here tomorrow. I love you and I need you.
I see you, and I understand.
I'll always be here for you, no matter what. I'll always love you, and you can tell me anything, and I won't leave you.
You made a terrible mistake and yes, you hurt a lot of people. But you are still a good person. Don't beat yourself up anymore or tell yourself you deserve less than. You are loved. Come out of this dark place of yours. If you don't you will die. Time to start thriving!
1) I'm a schizoprenic, and I want to talk to you.
2) (Anything that shows "I" care)
3) (Anything that makes me think)
Or if all fails to meet my expectations, know that your actions speak louder than words!
I know there is nothing I can do to stop this. But the least I can do is to be with you in this. I'm gonna support you. You are gonna go through this holding my hand. When you'll cry, you'll cry on my shoulder. I won't ever leave you. I'll always be there, to help, to listen and to make you feel better. I promise.
You deserve to be content.
You have worth, and I won't abandon you
