If you have any issues in your personal life that may affect your ability to perform well in law school, you might want to think twice before wasting $1000s of your dollars and time.
I agree with this statement 100%.
My concern here is that you still aren't accepting your responsibility in the drama that played out. "The rift was not my doing." First, what your roommate did took guts. As a friend who has had to tell someone that they needed professional help to deal with their problems, it is really scary. (And you are not "playing the psychologist" in telling someone that they need to talk to a real psychologist.) You do it knowing that it jeopardizes your relationship with the person. Saying it in person is completely awkward, and a lot of people choose to do it in writing. While you may think Facebook message is condescending, you should be grateful that your roommate had the guts to let you know that you needed help in the first place. And it was likely her plea for help too... "I
can't be your psychologist anymore!" It seems you unreasonably acted out against your roommate and caused a lot of the drama that you are now escaping. Your personal problems had started to impact your roommate's lives; it is time for you to apologize to them so you can all move on. I also imagine that you are developing quite a lovely reputation at the law school. These people are your network. You need to clear this up.
The kidney infection excuse is weak. I've had one too. There is no reason you can't study while recuperating, and that's the way the deans saw it too. The cousin's tragic death is extraordinarily sad. But I've had that happen too, unfortunately. It should not have crippled you, and you should have been able to at least read within two weeks or so. People all around the world go about their daily lives (even if morosely) after the deaths of someone they loved.
You have to own your own role in this. You seem to think that your "personal problems" are external forces that are causing you these problems, but the problem is more in your internal reaction to the drama. You create more. The part that is broken is your reaction, and that's the part that you haven't even begun to fix.
Also, your thread title seems to indicate that your story is not atypical. A lot of people like law school, do well (or don't, and still like it), make friends, and get good jobs. It sounds like you were not ready to handle additional personal responsibility with your depression and personal problems, but I don't think that this is a common experience at all. (Or maybe it is? I just don't know very many people who follow stereotypes from Paper Chase.)
