There has been an outpouring of tributes to Stone Temple Pilots / Velvet Revolver singer Scott Weiland since he was found dead on his tour bus Dec. 3. In response to it all, Scott's ex-wife, Mary Weiland, has penned a poignant and devastatingly honest open letter via Rolling Stone.

Though Scott Weiland's cause of death has not been officially determined, reports indicate that cocaine was found on the vocalist's tour bus. Weiland struggled with addiction for over two decades, which took a gigantic toll on his professional and personal life, the latter of which is discussed candidly in Mary Weiland's essay.

Here are a few excerpts from the Rolling Stone article:

December 3rd, 2015 is not the day Scott Weiland died. It is the official day the public will use to mourn him, and it was the last day he could be propped up in front of a microphone for the financial benefit or enjoyment of others. The outpouring of condolences and prayers offered to our children, Noah and Lucy, has been overwhelming, appreciated and even comforting. But the truth is, like so many other kids, they lost their father years ago. What they truly lost on December 3rd was hope.

Even after Scott and I split up, I spent countless hours trying to calm his paranoid fits, pushing him into the shower and filling him with coffee, just so that I could drop him into the audience at Noah's talent show, or Lucy's musical. Those short encounters were my attempts at giving the kids a feeling of normalcy with their dad. But anything longer would often turn into something scary and uncomfortable for them. Spending so many years immersed in Scott's multiple illnesses led to my own depression; at one point, I was misdiagnosed as bipolar. I feared the same would happen to the children. There were times that Child Protective Services did not allow him to to be alone with them.

Noah and Lucy never sought perfection from their dad. They just kept hoping for a little effort. If you're a parent not giving your best effort, all anyone asks is that you try just a little harder and don't give up. Progress, not perfection, is what your children are praying for. Our hope for Scott has died, but there is still hope for others. Let's choose to make this the first time we don't glorify this tragedy with talk of rock and roll and the demons that, by the way, don't have to come with it. Skip the depressing T-shirt with 1967-2015 on it – use the money to take a kid to a ballgame or out for ice cream.
