Almost all of us ask that question at some point. Reasons aren't what we truly want; we want comfort and we want to make sense of things. It's not logical that an adult would rape a child. But it happens, and we're the survivors who often can't figure it out.
Too often we blame ourselves with sentences that begin, "If only I had . . ." or "If only I hadn't . . ." We want to believe we live in a rational world with explanations for everything.
Sometimes there are no explanations, only facts.
I don't know the reason I was victimized; I do know I don’t want to live my life as a victim.
Instead I ask, "How do I continue to heal?" It's a much better question—and there are answers.
