I need a defining moment of strength, what should I do?

I've had very controlling parents all my life. They have binding obligations over me. I've mostly resented their plans but gone along with them because of obligation. Now that I graduated from college I found a job in the city but it wasn't good enough for them. I had my own plans to work and pay my way through one more year of school but they won't allow it. So they have offered to pay my way through another year of school if I stay here and don't take the job in the city. I've taken them up on the school offer but I feel so immobilized. They have never been emotionally available for me but easily open their pocketbooks. I'm incredibly sad. The love of my life is in the city. I know it would be best for us if I kept my distance from him for just a little longer while he finishes school. But I don't have any support here. My family is icy. My boyfriend is far away. I need to be strong but just don't have any support right now anywhere. How do I find the strength in my loneliness?
