Nicholas' College dream

My son Nicholas is a wonderful young man. He wants to be the first in our family to go to college and become a Registered Nurse so he can help people. Working in the always changing and stressed filled Emergency Room. He wants to always be busy assisting those that can't help themselves. After he becomes an RN he wants to go back to school to become a nurse practitioner. He has received some of the money for some of the costs, but he is still short. I feel like a horrible parent and will get a second job if needed, but we have also taken on my 7 year old nephew as our foster child and am planning on adopting him within the next couple of months. Leaving him longer in the day without me wouldn't be good. We also have a 12 year old daughter that also needs me at home at night as my husband works swings and I work  days.  Thank you for reading.
