Mabel-chan, I am so sorry to say this, but...
You never really "conquer" your trauma, my cute little half-elf; it just doesn't work that way for living beings with biologically mammal-type brains.
You can learn to accept it, live with it, draw strength from it; some of us just drink and try to bury it (do not recommend; 2/10)... but it's never conquered, I'm afraid.
Even 40 years later, it'll come to you in your dreams... but that doesn't mean it rules or ruins your life.
