CNA- Do Over

I took a CNA course a couple of years ago- and unfortunately, due to a very intimidating, harsh, instructor- I quit. I had an "A" on all of the bookwork material, it was just when I went into the clinical practice, I froze. When I asked the "instructor" how I could level out or let go of the tension, she just said "I don't believe nursing is for you- I think you should quit." Her statement took me totally by surprise and really shook me. I was devastated and with my spirit broken- instead of brushing it off- as I think I should have-I quit. I took my B/P monitor and stethoscope back to where I had purchased it- I could not even look at it or talk about the incident- for a long time.

I quit that CNA class, but that did not mean my dream of being a nurse died- this despite my return to college Spring 08 to pursue a Master degree in a field-- I wasn't all that excited about-- that I chose to quit when I completed the semester-- (I had to ask myself "who am I, why am I here?") The degree program just did not hold the interest in me that Nursing does. And Nursing, being unrelated to my undergraduate study (Communications/English) I know that in order to pursue it, I'm going to have to get that CNA ...

Could anyone share positive CNA class and field experiences that make going through the mess I encountered before, worth it? I just want to know if others had to develop an outer shell to deal with some people- those who you initially thought were there to encourage you?

At 33, married w/children, I know I want to pursue Nursing. I hope being a part of this forum will help me to- I know there will be bumps in the road ahead, I just would be so grateful for some advice on how to get through them all!

I will so appreciate all the advice
