Question : Eclipse - Why cant I open my project?

I have been working on a Java eclipse project. (in Windows)
and I think I may have pressed close-all in the File menu. So, my Eclipse is completely blank. There is nothing in the hierarchy tab.
Now, restarting, when I open the project name from the file menu, it is empty.
It is like a blank project
Even when I go 'switch workspace,' it is still an empty workspace.
The window name doesnt even change to indicate the new workspace's name.

The code still exists. How do I open up a workspace I have just been working on?

try importong the project Import>Import existing project
