Hello. I've seen your request how to find your mappings back.
Just open this internet page:

or this one:
https://www.openstreetmap.org/user/akshajravuri
https://www.openstreetmap.org/user/akshajravuri/history#map=5/12.072/100.192
Now you see a number of changesets made by you.
Select a changeset and open it in your editor. It shows your mappings.
Best regards
