Changing careers at 17 years into a job, is it realistic? (update)

I want to move from home health aide to something with more stability. Thank you in advance. My family is supportive but nervous. 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 2 months.

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