The Moms of Michael Brown, Trayvon Martin and Sean Bell Speak Out

Sybrina Fulton. Lesley McSpadden. Valerie Bell.

Three mothers who know the grief of losing a son too early met for the first time Sunday.

Fulton, the mom of 17-year-old Trayvon Martin – who was killed in 2012, and Valerie Bell, the mom of 23 year-old Sean Bell – who was killed by a barrage of bullets in 2006, had words of comfort for Michael Brown's mom, Lesley McSpadden.

"You have to focus on the good times, you have to focus on when he was smiling, you have to focus on his first day of school and Christmas Day," Fulton told McSpadden.

"Put a picture up when he was happy and focus on those, just don’t focus on the death, because that’s going to eat away at you."

When CNN's Don Lemon asked the women if they communicate with their sons – they all said yes.

McSpadden said especially when it rains.

"There's something about the rain, something about it… I feel him."

Fulton told her: "He's there, hes watching over you."

Brown, the unarmed teenager who was fatally shot in Ferguson, Missouri, on August 9, will be laid to rest today.

Fulton said the service will be, for McSpadden, the "worst day of her life as a mother."

"There is no words that can bring comfort to her as a mother by seeing her son in a casket."
