There are two things that I just don't get about Ralph's health.
1) when you get a kid, your priorities are supposed to change. And I think for a lot of us, we start worrying about our own health so that our kid is taken care of. The normal human being wants to be there for their kid.
2) apparently no one in Ralph's life has any willingness to get him help. If I pulled half the shit that Ralph pulled, I would have people publicly cutting me out of their lives, and encouraging others to do so, if I refused to accept help.
