An emotional Diamond Reynolds described the trauma of watching her fiance, Philando Castile, be gunned down by police in front of her eyes during an interview on an Oprah Winfrey Network show.

Reynolds made an appearance on "Iyanla: Fix My Life," hosted by author and inspirational speaker Iyanla Vanzant, in a show that was broadcast on Saturday evening.

If you're not familiar with the show, it sees guests "pull back the curtain on what is broken" in their lives, before Vanzant's counseling hopefully leads to an emotional breakthrough.

Reynolds was asked what she would say to Jeronimo Yanez, the former St. Anthony police officer who shot Castile dead during a traffic stop in 2016, in front of Reynolds and her daughter.

"I want you to know he scarred me and my daughter for the rest of our life, you exposed to our deepest fear, that's losing someone who really loved us and had our best interest at heart, and took away our best friend," Reynolds said.

Yanez was found not guilty of manslaughter following a trial last June.

Vanzant had another guest on the show who provided advice to Reynolds, the mother of Trayvon Martin, who was shot dead in a gated community in Florida by a neighborhood watch member.

"There are people who will help you, there are people who will support you," she said, adding: "Even though I didn't understand what happened to my son ... I had to trust in God, I had to believe in God, and I needed to open my eyes to what he was trying to direct me to do."

Here are some excerpts from Reynolds' interview.
