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 are not a burden. you have value.
"I'm sorry for everything."
I will never leave you, we'll pass through everything together, believe me.
Im sorry I hurt you so badly. I cant even start to list all the horrible things I did to you. I was so lost trying to figure out all the possibilities in life, I never realized it was you I wanted all along. I love you.
You do not deserve to be judged
You're an amazing and powerful person and you can overcome anything.
I
Everything will be just fine. I promise.
You're not a complete failure and burden.
You are doing okay right now...don't worry about what you need to do next for once
