I'm ready to take the big step to go back to college... But?

Recently, I got out of a bad relationship... Now, I know that 23 years is still very young. But, the break up just kind of made me realize... I want to know that if I should have to grow old alone or simply need time alone... That I can take care of myself to the fullest extent. And, this has all just made me ready to do everything I need to do to become independent. I'm so tired of living with room mates or family. So, my question is... What would be good majors that would provide me with good opportunities and an independent future? I know a few of the obvious choices such as nursing and what not. But, what are some others. I don't have to be rich. But, I want to know I'll have my own back.

I went to college once when I majored in Early Childhood, but I backed out because I had no way to get up and go when I needed to. I didn't have a license and so I had to depend on everyone to take me anywhere. Them having their own lives I couldn't ask them to drop everything and drive me just ANYWHERE. Well now I have a DL and a car. But, I've been thinking about it and my own cousin who is a teacher said she can't afford to live on her own, how would I? So, again... What majors whould provide me with the opportunities to be an independent woman?
