Demi Lovato has faced an intense sobriety battle, but she is well aware that she is not alone.
She has taken to social media to mourn the sudden and tragic loss of her friend, Tommy T.
As she grieves his passing, she reminds her fans and followers that addiction is a terrible disease that has claimed yet another beautiful life.
"Addiction is NO joke," Demi writes in her Instagram Stories.
She continues: "heaven gained this beautiful angel last night because of that terrible disease."
Along with her words, she includes a photo of Tommy.
"I'm crushed," Demi expresses. "And will always miss you @sirtruss."
She then tells her followers: "If you or someone you know is struggling please know it's okay to ask for help."
"Devastated," Demi writes in another post to her Instagram Stories.
She encourages her fans and followers: "Please hold your loved ones tight."
"Tell them they are special," Demi advises. "And that you love them,"
"Make sure they know it," she suggests.
Demi's post concludes: "RIP to my boo @sirtruss"
Tommy T was also mourned by other loved ones, including his friend Gabe.
"You were like a brother to me," Gabe wrote. "You made me smile when I was down, you always helped me out whenever."
"You truly cared about me," he added. "And you gave us all laughter."
"I remember last week we were talking about life goals," Gabe recalls in his tribute.
"We always talked about things that mattered," he added. "And how we strive to become better versions of ourselves."
Gabe concluded: "We will all miss you Tommy. Rest in paradise."
Addiction and its potentially fatal perils are no strangers to Demi's life.
The beloved singer and actress has battled with addiction more than once.
Last year, after more than half a decade of sobriety, she relapsed and began consorting with the wrong people.
In the summer of 2018, she overdosed and was rushed to the hospital.
There were real doubts that she would make a full recovery. Addiction is a horror.
Demi has been working hard for months -- on her music but also on herself.
Just a few months ago, fans grimly marked the one-year anniversary of Demi's near-fatal overdose.
Considering how long she had been sober before her relapse, she knows that she's not fully out of the woods.
Not all addictions are equal, of course. Most people could end their dependency upon caffeine if their lifestyle changed, for example.
But when Demi discusses addiction, she means the compulsion that nearly claimed her life, and which has taken the life of her friend.
Demi's message is so important -- and it's key that she referred to addiction correctly, as a disease.
Those of us who do not experience true addiction may find it easy to dismiss it as a "persoanl choice."
We must always remember that our experiences are not universal.
Just as the flu can go around and skip over some people entirely, addiction doesn't impact everyone -- but some cannot help but be its victims.
Neither Demi nor Tommy chose to be addicts. Our hearts go out to Demi and to all of Tommy's loved ones at this time.
