What is it that confines you? What is it that won't let you play, talk, or interact? What is it that says you can't write, or you'll never sing? What is it that says you're not as good as someone else, so "why try?"
What are any of these crippling psychological programs inside of the consciousness of humanity empowered by other than this: the moment that we feel them, the reason we won't challenge them is because they come with a great pain that says, "If I'm going to even think about this, all I have to look forward to is humiliation and failure." Then the pain appears because of your resistance to an imagined condition. Your past is an imagined condition... no matter what happened to you! Did it happen? Yes. Is it happening now? Only if you re-dream it.
You can choose a higher view by realizing that whenever you hear or feel yourself thinking something like, "I'm terrified of this situation," or "I've been through something like this before so I know just how bad it's going to be," you're adding (without knowing it) one more bar to a prison that, as it's being built, is promising you that when you finish it, you'll either be safe or have new possibilities.
Shatter it! It's simple. How? Wake up now. Understand that in order to leave the world of limitation, you have to leave it. The only way to leave the world of feeling sorry for yourself isn't by thinking about how miserable or afraid you are, or who or what made you that way. You actually have to deliberately leave that world of thought -- the world of dreams. And what world do you enter into? Don't worry about that! Leave the one, and the willingness to leave the one is the entrance into the other. The new world will educate you about every subsequent world that exists concurrently. Then you'll know what your true higher possibilities are because they can't be named, they can only be lived.
