Write about all the things about which you have a deep fear. Fear deep enough that you probably alter your actions in some way because of it.
Next, pick one of said fears and free write until you trigger a sense of outrage in yourself, a sense of “how dare you?”-ness to that fear.
It borders on silly, but I do this each time a fear registers in my mind and it has never once let me down. Even big, fucked up things. Sometimes it takes a little while of writing into it but srsly. Give it a try.
