I think what you are doing for your mother is wonderful. Being a nurse is about taking care of other people and that is exactly what you are doing. Keep your head up and be proud of yourself. I'm sure next semester you will be sitting in the front row. :)
I start classes at OU Southern September 6th. We have had 1 orientation and we have another September 1st. I am so excited and scared at the same time. LOL. Good luck to us all!
