Bite the bullet and stay at home with your parents. After you graduate without any additional debt, you'll be glad that you did.
It's not bad if it's the only loan you're planning on taking. Even if you take it this year and next year, I've heard of worse. The main thing is knowing that you can pay it back when you graduate. Don't take out such a large amount that it becomes a burden, even when you start to utilize your degree.
It sounds like taking a semester off and being home would be hell for you. That in itself would be worth the cost of the loan.
