Burning out 25days before my attempt - CFA L2

Hello all, I know this could be googled but I really wanted to know from the CFA candidates themselves.
How do you deal with a burnout?

Situation: I feel tired and drained to even sit and revise the readings. I feel tired even before opening the book. I try completing 2 readings a day, solve some ethics and if I have it in me, I'd solve a few questions. Today, I just did one reading and started solving some questions but it feels like I don't give my best while solving and that I solve for the sake of it.

I really don't wanna risk letting loose of my prep at this stage.
