The Bad Girls Secret

Every individual has experienced their own traumatic experience, whether it was due to love, hate, friendship or family... this of course concludes in their new way of thinking, interaction, and personality. Only to help protect themselves from ever happening again.

But,
What happens if that traumatic experience was so bad that it caused an individual to forcefully remove it from their memories? How will they ever develop their own self defence to help defend themselves if it ever happens again?
What if, it does happen again?
