Two weeks on from the helicopter crash that tore apart her world, Vanessa Bryant has shared her most emotional message yet about her grief at the death of husband Kobe Bryant and their teenage daughter Gianna.

The widow and bereaved mother said she is having trouble accepting the reality of her losses.

“My brain refuses to accept that both Kobe and Gigi are gone. I can’t process both at the same time,” Vanessa wrote in an Instagram post on Tuesday (US time.)

“It’s like I’m trying to process Kobe being gone, but my body refuses to accept my Gigi will never come back to me.

“It feels wrong.”

Vanessa, a former model who worked in the art department for films including Man on Fire before marrying the NBA star, revealed the only thing keeping her going is that she needs to “be strong and here” for her three surviving daughters.

“Mad I’m not with Kobe and Gigi but thankful I’m here with Natalia, Bianka and Capri,” the 37-year-old wrote.

Natalia is 17, Bianka is three, Capri is seven months old.

Bryant and 13-year-old Gianna were among nine people killed when his helicopter crashed into a Los Angeles hillside in bad weather on January 27.

The group was travelling in Bryant’s helicopter to his Mamba Sports Academy at Thousand Oaks, California, for a basketball match.

Gianna, also known as Gigi, was to play and the NBA superstar was the team’s coach.

In a preliminary report released on February 7, investigators from the National Transportation Safety Board said just before the helicopter crashed it hurtled toward the ground at faster than 1200 metres per minute.

It showed no clear signs of engine failure.

A final report with the best assessment of what caused the crash could take up to two years.

Vanessa has since used social media to express her devastation at the deaths of her husband and daughter.

Just days after the tragedy, she acknowledged and expressed gratitude for the global outpouring of support.

“Thank you for all the prayers. We definitely need them,” she wrote.

She shared a video of Gianna playing basketball, and revealed more about her heartache about outliving her daughter.

“Why should I be able to wake up another day when my baby girl isn’t being able to have that opportunity?! I’m so mad,” Vanessa wrote.

“She had so much life to live.”
