Lost my wallet at Juhu beach :(

Hi guys, it was my very first visit to Mumbai and Juhu beach. I visited the beach at around sunset time between 4:45 to 6pm today. When I reached home I realised that I have lost my wallet :( It was having all the important documents like Aadhar, PAN, DL, Debit card and more. I’m feeling so worried and scared that my documents will be misused . Can anyone please guide me on how can I get my things back or atleast help me with securing my identity so that no one can impersonate me.
