Wednesday, the brother of Grande, Frankie Grande, took on social media to mourn the 26-year-old rapper's death.

"I'm beyond heartbroken by Malcolm's death," Frankie began. "It was a good friend and it was wonderful for my sister." That's the reason I went to the Rehab Center where I felt detoxified from all the drugs and medications that I took it, while I could not imagine living without them.It was the place where I found the support community that showed me that living without drugs was a possibility and I would never have discovered that without Malcolm, I remember when I would have 30, 60 or 90 days of cleaning and Malcom would be there with a gift, a card and some words of encouragement … telling me that he knew how hard it was to stay sober and how impressed he was that I was successful.

"Drug addiction is a TERRIBLE disease … a lot of people are addicted as I am and many of them are losing," he continued. "Those of us struggling with addiction need to stay strong, we need to continue working hard every day and helping each other – our illness is strong but WE ARE STRONGER and I promise to work every moment of my life. life to keep me sober so that I can be there for others.This is a difficult road but YOU DO NOT HAVE TO TRUDGEZ ONLY. "

"Anyone who needs help, the help is there," Frankie told his supporters. "You just have to have the courage to ask, what I know can be EXTREMELY difficult … but when you do, I guarantee you that the support will be there.Do not be ashamed if you lose the battle against the addiction, shame feeds sickness, humility defeats him, please ask for help, you're not alone! I'm here … and I'll continue to to be there … for you … Malcom my friend, we will miss you very much, look at me from the sky, proud for every day I live my own sober life … 453 days and counting … Thank you for bottom of my heart.
