I'm so sorry that you had to experience seeing someone you love pasted all over the news. I'm sure that hurts deeply.
Unfortunately, it's another one of those things that we have no control over. I know I don't understand the addict in my life. I can't truly understand something that I have never experienced. But with daily work, I do find that I am getting better and better at controlling my reactions (most specifically pain) to his behaviors and actions. Limiting my exposure to him has certainly helped me in my efforts to lead a healthier life as well.
Embracing that which we do control and releasing that which we have no control over is liberating......but it takes a lot of work (at least it did for me.....I must be a slow learner).
Take care of you.
gentle hugs
