Changing careers at 12 years into a job, is it realistic?

My layoff made me rethink whether to stay in my field. Any experience at all would help. I have good customer skills and I am comfortable with spreadsheets. Has anyone made a similar move?

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

I began with informational chats, then a short online course, then a related entry-level role. It took about 5 months.
