Career change after a layoff, where to begin?

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 good customer skills and I am comfortable with spreadsheets. How did you start?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

I began with informational chats, then a short online course, then a related entry-level role. It took about 7 months.
