Changing careers at 9 years into a job, is it realistic? after 9 years as a nurse's aide

After 9 years as a nurse's aide I am thinking about moving into a different field. I have read a lot of threads here and could not find my exact situation. I have a little time and a small budget for training. Did you take a pay cut?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
