Burnt out! Does it get better?

Hello! I have been working close to 9 years in customer facing roles and I think I’m done, extremely burnt out. Thought switching would help turns out it made things worst

Does it get better in non customer facing roles? If so, how do I move to the other side?

Or should I just quit and backpack for a year or something 🥲

If you have overcome a burnout, how did you do it?
