Kids leaving home for the first time.

My daughter graduated back in May of 2008. She decided to take at home college course for photography, so we thought she was going to stay around here so it wouldnt be so hard on her. But she came home yesterday and told us she gave her 2 weeks notice at her job, and she was going to start her life. She went to look at an apartment in Sioux Falls. Her dad and I are very scared for her, as she has a car payment, looking at an apartment that is 630.00 a month. The only good thing about this is one of her high school friends decided to room with her and cut things in half. But still that is going to be 515.00 a month not including electricity and internet access. She will have to hold down a full time job, plus do her 3 college courses daily and maybe take a second job. If anyone out there has anything to say that can make me this easier on me or has any suggestions please let me know. I am so scared for her.
