Fucking Sober

I don't understand addiction maybe as much as I should. I have been clean and sober off of alcohol and cocaine for over two years now and I watch others still struggling in the grip of addiction but I don't understand why they can't get themselves out. Sometimes I feel like I'm very privileged in the sense of the fact that I was able to put down the things that were harming my life and I need to remind myself that others don't necessarily have that strength. But when I do talk to friends and they tell me that they don't want to get clean it's almost offensive to me that they don't care about themselves as much as I care about. But I also feel like is selfish thing to feel. I wish that I knew the right words to say to somebody to make it click but I guess you can't force something that's not wanted
