I lost the stash. But since I was using IntelliJ all through for coding, it kept local history of all the file for almost 1 week.
How I recovered my files using IntelliJ? http://www.jetbrains.com/idea/webhelp/viewing-local-history-of-a-file-or-folder.html#
After that I created a patch (right click on file and time when you thought your changes were stashed) and carefully selected only those files that were modified by me.
Now apply the patch and you are good to go.
