Hey Don't feel bad. I was in your very same shoes. I had a stressful sitaution dealing with, being a single parent, and having to work fulltime in the ADN. However, after I got over the emotional trauma. I went to a major university transferred my hours. IN ONE YEAR I Got a bachelors in Liberal Art and a Minor in Criminal Justice (with honors I might add). Then I applied to an Accerlerated Nursing Program (I year program to get ur BSN not ADN

), because they only take you when you already have a degree and I am in the program right now.
So my advice to you is that, there are many options around you. You know what to expect next time around. You know the manner in which the nursing questions are asked

so you will be fine.
Stay focus and do not give up on your dreams!!!!!!!!!!!!!!!!!!!!!!!
