Self sabotage is something many people deal with. I recently had a "spell", more a chant, come to me that I think may have been shown to me by a fairy its very simple. When you start or feel like you may or are engaging in self sabotaging behavior chant this to yourself and truly believe in it as your only hope of overcoming your self sabotage:
"Happiness without consequence."
that simple just keep repeating it in your head to your self or out loud.
