If the choice is between burning out and taking a sabbatical to get a break, take the sabbatical.

My only advice is: structure the sabbatical in some way. Give yourself some OKRs. Doesn't matter what they are. If you don't you'll find yourself at the start of the last month wondering where the time went (and, in my case, extending another few months).

Second piece of advice: set up a job to return to before you take the break. Once you leave the company/organization, regardless of the terms, it's much more difficult to line up roles. Lining up a role is never a guarantee, of course, but it's better than waiting until the last month and trying to get rehired.
