I've been in your place Rebecca, only it was a daughter and she didn't hurt anyone, but she was a cop at the time and it was plastered all over the newspapers, social media, and local TV.  Alcohol was her drug of addiction.  My advice to you is:  1.) Stop making excuses for your brother.  He made his choices and he is the only one who can change his life. 2.) Stop reading the online comments for your own sanity. You will not find anything there but more pain.  3.)  Get yourself into an Al-Anon program.  The support you will receive there is amazing and  you will meet wonderful people who will not judge you or attack your family.  Also, you will learn the difference between loving and supporting vs. loving and enabling.  4.)  Have hope.  My daughter turned her life around and has now been sober for more than 3 years and is halfway through getting her college degree.
