To the OP, I am a graduate of a non-nursing degree, and am also seriously considering a DE MSN degree, and hitting blocks like you when I mention I want to change my career as a nurse. It is frustrating and depressing to hear when other nurses that you think would support you in entering healthcare would suddenly shut you down.
Have you considered doing a double major or doing nursing as your major and the other field as your minor? If you’re still doing your undergrad but really have your eyes set on nursing and NP, then that would be my advice for you.
But if you’re set on DE MSN, then go for it and know I’m going with you.
