Changing careers at 5 years into a job, is it realistic?

My layoff made me rethink whether to stay in my field. I am in Dallas, in case local advice matters. I have good customer skills and I am comfortable with spreadsheets. How did you start?

Keep everything in writing and save the confirmation numbers. It saved me later.

You likely have more transferable skills than you think. Write down what you did, not what the job title said.
