I just listened on Spotify. Fred is obviously going through some shit that I've never experienced so kudos to him for being so open and honest about it. Like anyone speaking out about addiction or mental health issues, it takes a lot of fucking guts just to admit you have a problem and get treatment. It takes even bigger balls to speak about those issues live on the radio knowing there are millions(?) of listeners and hopefully that will encourage people that need help to get it.
For good reason, Fred sounded a bit nervous when he started discussing it again and to me it didn't sound like he intentionally left anyone out because it seemed like a stream of conciousness thing where names just come to him. If it was intentional, it's kind of a dick move on both of thier parts but we have no idea what's going on with Rich either.
For now, I'm done speculating on whether or not there is an issue between them, I'm just glad that based on what he said about his family's excitement, that he's truly commited to getting better.
