Changing careers at 16 years into a job, is it realistic?

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. My family is supportive but nervous. Has anyone made a similar move?

I took a small pay cut for a year, and it was worth it for the growth afterwards.

I began with informational chats, then a short online course, then a related entry-level role. It took about 2 months.
