Well the OP is probably looking for extreme cases.. i.e. someone who is obsessed to the point they actually put EVERYTHING else second, their job, their family, their partner, their kids perhaps. I'm thinking beyond extreme here, like buying diamond-studded collars while the family has to eat Ramen noodles LOL. I could be wrong though.

Still I think it's rather odd to come to a message board looking for this type of thing. I'm not sure what to think but like Robin, I don't think the OP came to the right place .
