You might have addressed this in an earlier thread, but I think it bears asking again anyway, Liz: is this license for which you're studying what you really want to do with your career?
I'm not suggesting it isn't, and it's possible that all this other crap that's happening over which you have no control is getting to you, but I know that when there is an obstacle standing between me and something I want very much, there is almost nothing that can stop me from doing everything I can to prepare to tackle it.
So I guess the question is, is it time to start asking yourself why you're doing this, or is it time to focusing on letting go of the things you can't control so you can focus on the things you can?
