I haven't read this entire thread, but I want to say please do NOT defer your loans unless you have no other choice. I deferred mine for much too long when my son was little, and now my student loan debt has doubled. At the present rate, I will literally be paying it off until I'm 70. I'm hoping for a miracle on that one!
The other thing I want to say is, as long as you're being supported by/living with your parents, you pretty much have to deal with whatever they have to say. You always have the option of living on your own and supporting yourself, and then you can do what you please. I worked full time while going to school full time, through four years of college -- and pulled a 3.8 GPA. It's not easy, it's obviously not the ideal situation, and I don't recommend it if you have other options - but it can be done.
