Changing careers at 12 years into a job, is it realistic? - 10 months and counting

My layoff made me rethink whether to stay in my 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. Has anyone made a similar move?

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