Changing careers at 7 years into a job, is it realistic? after 7 years as a medical assistant

I want to move from medical assistant to something with more stability. There are 7 people counting on me, so I am trying to be careful. I have a little time and a small budget for training. 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.
