School..Again??

Last semester, I enrolled at a local college to attempt to finish my degree...in what was the question. I prayed about it for a long time, then through that prayer God spoke to my heart and told me it just was not the right time in our lives.
This college wanted me to enroll in a Physical Therapy Assistant (PTA) program, which is what I registered under but just didn't "feel" it. All I kept saying was I just really want my nursing degree!!!
Right after my mom died, and I came home from the 4 year college where I was living on campus & attending, I took some classes at a local community college to try and stay on track to finish my degree. So randomly today, I got on thier website to see what it would take for me to finish my education.
I was plesantly surprised, as I checked out there online classes to see that ALL of the prereq's I would need are listed online. To further aid in my joy, there are several classes I had already taken are listed on the prereq's for the associate in nursing degree, which means that if I were to enroll there in the winter, I could take those prereq's from home as online classes, then the core nursing classes are listed as day/evening/week-end classes.
This flexable class schedule would enable me to finish my degree; according my calculations, in 18 months!!!!!!!!!!!
Now, I am back to praying again. Is this the right time in ourlives? I feel this sense of urgency to get this degree done so that it can stop looming over my head. There are just so many more things that play into this decision now that I am a mommy and wife.
To further complicate this decision, we really want to have more babies. However, it would be more complicated that it is right now to continue my education with more babies. Yet, with me finishing at a community college my credits are still good for three years( for science classes), so that I could stop when we have another child then start again when I/we are ready with a timing penalty.
It is our strong desire to send our children to a christain school. It is my belief that I will need to work to help pay that tution. And it is my question, that if I am gonna work part time, I should make enough to afford something other than the gas to get there and the car payment!!!
I am praying that God will just make himself evident in this decision and provide away, if it is His will.
