I have been pretending to care too, which is what scares me. How long will I do things in life because I pretend to care about them? And 12:49, I thought that's what it was also, but considering the feeling carried all through most of last semester, got stronger throughout summer, and is now at an all time high with school back...I don't know how temporary it is.

You are obviously overwhelmed with something and have gone numb. This happens to me every once in awhile. I get saturated and then decide it's less painful not to care. The feeling passes after awhile, it's not permanent. Maybe it helps to remember that everything in life is temporary... even the good stuff, so make the most of the good stuff and minimize the bad.
