1. Don't panic.

2. Make a backup copy, *including* the .git directory (very important!)

The .git directory contains your 4 day work, and it is very likely still retrievable.

It may be a simple matter of

   git branch the-lost-state HEAD@{1}

If you can't work on a command line, then git extensions certainly has some nice UI that lets you create a branch at a particular revision. In this case, the branch name is "the-lost-state", and the revision is HEAD@{1}.

You can try more branch names at HEAD@{2}, HEAD@{3} (you get the point). It means, roughly, "the state where HEAD was 1, 2, 3, etc. git operations ago".
