What to do about the current situation as an As student

Salam sir,
I wanted to know what I should do right now concerning this current situation because I was fully prepared for the exams in may/June but now that they have been shifted I don’t know what to do I can’t relax because of this and am in a constant state of anxiety because I can’t find the motivation to study since they have been shifted. Could you please guide on how and what I should do.
Thankyou
