I Have to Work Full Time

I have recently enrolled in college, I have 50 college credits and have decided to go back to either earn a bachelor's degree in Social Services or become certified as a LVN. I have 2 children at home whom are in high school this is going to be a challenge for me as I have to work full time and will be enrolled in classes full time. My grandmother has been gone for 21 years now and she is my inspiration she worked very hard and never let anything get to her, I want to better myself for her.
