“I had so much self-discovery to unlock and explore. I knew in this very moment I would allow myself to take back my light, show victory over my internal battle of self-respect, and brave this world with piercing clarity,” she added.

Simpson said cutting alcohol out of her life was critical to achieving this goal. She said the intoxicant “kept my mind and heart circling in the same direction and quite honestly I was exhausted.”

“It was very real for her,” the source said. “She spent half the day crying. It meant so much to her to hear from people, hear their stories and know that she helped even one person.”
