Is it worth it to spend $56,000 for a master's degree?

I’ve been thinking about getting a master’s degree in OT for awhile, but the only college I can go to in the state I live in (unless I want to live in the middle of nowhere) is a private college and would cost $56,000. My other school loans are paid off and i’m not in debt. That’s alot of money though it scares me! and how will I be positive I will like that career? It’s hard to know 100%..:(
