Cindy Crawford's heartbreaking post about son Presley Gerber just two months before his death at 27

Cindy Crawford shared a 'proud' Instagram birthday post to Presley Gerber two months before he died.

Presley Gerber died at the age of 27 years old, his death confirmed by records filed by the Los Angeles County Medical Examiner.

The son and eldest child of Cindy Crawford and Rande was at a rehabilitation center in Los Angeles.

It follows his family having spoken out publicly in support of him, from commenting on his own social media posts being open about his struggles, to mom Cindy sharing a birthday post for her son two months ago.

Crawford took to Instagram on July 2 sharing two images; the first, a photograph of her and Presley from when he was little, him lying across her chest.

The second image shows the pair when he's more grown up, both wearing coloured sunglasses.

The caption reads: "Happy birthday @presleygerber I’m so proud of the man you’ve become, but I’ll always see you as my little boy! Love you."

Since the news of his passing, an Instagram has commented on the post: "My heart is so heavy for this family right now. I’m so sorry."

Cindy, Kaia and Rande had also been vocal in their support of Presley on his own posts to Instagram.

Five months ago, the family shared messages of support on one of Presley's final Instagram posts opening up about 'finding [his] way back to' himself.

In a post shared to his Instagram on March 26 earlier this year, the 27-year-old shared a video of himself standing in a garden, 'pre Ibogaine Flood Dose'.

"An ibogaine flood dose is the maximum, medically safe macrodose of pure Ibogaine Hydrochloride (HCl) administered to a patient," the Ibogaine Clinic explains.

It continues: "The goal is to completely 'flood' and saturate specific receptor sites in the central nervous system—primarily the NMDA receptors and the kappa-opioid receptors."

The process is designed to 'overwhelm and physically dislodge the synthetic drugs (like Fentanyl, Suboxone, or Methadone) that have hijacked your brain's reward center' in the hopes of 'completely blocking the physical agony of acute drug withdrawal'.

Though the clinic notes: "Because a flood dose is so immensely powerful, it places a temporary, heavy workload on your cardiovascular system and liver. During the flood, patients experience ataxia (the inability to walk) and an intense slowing of the heart’s electrical recharge time (QTc prolongation)."

Presley's post continued explaining the video was a 'quiet' one before 'everything changed'

Presley opened up: "I was absolutely terrified, and I knew I would be again if I ever had to face something like this (helps to not go into the situations you do that get ya there but that’s life sometimes.) (my mantras were love yourself and lis gotta be the last time for this reason. letting go of control didn’t come easy, but I trusted there was something bigger than me guiding it. I knew why i was there. I faced what I had been running from, and somewhere in all of it, i started finding my way back to myself …. We shall see….

"Praying it’s the last time I have to come back. Next time I’d like to choose And absolutely can’t forget the incredible caring kind and on their sh*t team. Helps a lot haha. And I made some dope ass friends there."

Kaia commented: "that’s my brother I am so damn proud."

Cindy wrote: "You are a warrior! Walked thru the fire to find yourself! So proud!"

And Rande resolved: "I’m so proud of you and your courage. Facing what’s hard takes real strength and watching you find your way back to yourself is everything. I love you so much."
