I have something I want to get off my chest.
What do you want to tell me?
I want to tell you something that I've never told anyone else.
It's good to tell someone your secret if you think they should know it. It can be difficult to keep something to yourself and letting it out might make you feel better.
Ugh! It's too embarrassing to say! I just want to!
If you have something to say you should just get it out and you will feel better.
