Missouri Mom's Heartbreaking Facebook Post About Her Son's Addiction Goes Viral: 'These Pictures Were Taken 7 Months Apart'

A Missouri mom's heartbreaking Facebook post showing how fast her son has changed because of his drug addiction has gone viral.

Jennifer Salfen-Tracy shared two photos of her eldest son Cody Bishop, which she said were taken just seven months apart.

The first shows him looking healthy but the second image is a stark contrast, Bishop is almost unrecognizable, his face more gaunt and his body looking much thinner.

"These pictures were taken 7 months apart," Salfen-Tracy wrote in her post on Wednesday. The post has since been shared more than 40,000 times.

"The face of heroin and meth...... is reality for so many people and families in this world today,' she wrote.

Salfen-Tracy, from Wentzville, Missouri, said she decided to share her story because many people were asking how things were going with her son.

Bishop was an athlete who graduated from Wentzville Holt High School in 2011, according to KSDK. According to his Facebook page, he started a job at All Inclusive Concrete Systems in March.

But Salfen-Tracy revealed that he is now homeless in Las Vegas and she hasn't heard from him in weeks. She added that Bishop is a father himself and it's difficult to understand how someone who has children "who love and need them live the life they do."

She wrote: "Cody is still homeless in Las Vegas and I have not heard from him in weeks now. Hearing how bad he is doing is hard but not hearing at all is worse. The unknown is what makes a person not sleep at night.

"It is hard to understand how someone who has families and children who love and need them live the life they do. I have turned it over to God and pray that he decides he is tired of living like this and wants to come home to get help. Through social media I have came along so many great people that have crossed his path over time through his past rehab," she said.

"They have a great support team with each other that is amazing and I appreciate those who have reached out trying to help. I just want to say thank you to those who have talked to him and thank you for all the prayers."

She finished her post with a plea for her son to call her, writing: "Cody if you see this please call us... we love you!"
