Having read your original post, I wanted to suggest that perhaps you try being part of some of the activities that you have thus far refused to participate in. The 'touchy-feely-ness' of them may turn you off, but I think you will see further depths in your fellow students. I turned down Yale to go to Columbia, but when I interviewed there, I met several of the students in the CNM program and I guarantee you that they are not all upper to upper middle class background. They are all finishing school with huge amounts of student loan debt just like you are... and many of them have very interesting experience working with pregnant and/or birthing women whether it be as a doula, working in international aid or teaching prenatal yoga. More and more women are going into midwifery as a primary career, not as an extension of a previous nursing career- and they make excellent midwives. Also, new midwifery students are getting younger and younger. I am in my 30's and am the oldest in my program (that I have met at this point anyhow). YET, I am finding that the younger women all have amazing backgrounds, depth and passion, despite their youth.
My feeling is that if you go to a school with a direct entry program, most of the programs will be geared towards those students. If you only want to be in school with people with previous RN experience then you should look into programs with no direct entry component. I hope this does not come off too harsh, it is not meant to be that way. But I think that if you make yourself part of your school's midwifery community (and that may mean exiting your comfort zone from time to time) your confidence and success will increase dramatically-- you may find the students eager to learn from your experience, and you may even find that you can learn things from them.
Good luck, whatever you decide.
