I assume YBS is...Yale (YSOM)?
I would encourage you to look at your priorities. Many of the "skills" one acquires in an MBA can be had through far easier and less expensive routes than an MBA. You go for the networking, career shifting, etc ability.
Personally, I've never understood the JD/MBA except in the case of entrepreneurs who will need to do a lot of their own legwork. No law firm cares if you have a an MBA, and (unless being hired for a counsel role) not many businesses would care about the JD (again, lest they want to exploit your bar membership for some legal work in addition to your other duties). If you want to be a lawyer, get a JD, which can be readily had straight out of undergrad. If you need a little business boost, pick up some books. Conversely, if you're looking at a business route, an MBA isnt going to do much for your hiring prospects in a lot of industries without more (full-time) work experience. Sure people get them straight out of undergrad, or with 1 year of experience, but at 22, 23, I didn't have a clue what I wanted to do long term (though i was cocksure had you asked me at the time). I'd say go to law school or go to work, then reassess.
Just my 2c.
