That makes sense. I'm glad your feelings are coming out of a well-thought out place. I would say that (for me, anyway) I am in an environment that is completely different from what I'm used to (call it culture shock, if you will) and I've done ok. In reality, all I needed is one or two good people to stick with. I would say, before you decide, use the time around second look to scope out not only the school, but the area locally. For me, church was a giant support system, and I found a branch of my church here, which made all the difference. Also, talk to that URM potential (if you have her contact) about her thoughts about attending. Also, if possible, ask admissions to be put in contact with the URM students and faculty there so that you have links even before you step on campus. This will definitely help you have the components of the support system you need. If there is a component of your normal support system (blood relatives aside) that you might miss being there, ask admissions (or the URM staff/students there) for how they gain that or if you can be connected to it locally. I hope this helps.
