Changing careers at 4 years into a job, is it realistic? - what worked for you?

My layoff made me rethink whether to stay in my field. I do not usually post, so bear with me. I have a little time and a small budget for training. Did you take a pay cut?

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