My main work project has the White Screen of Death

Yesterday I was trying to move my project to a public site on Digital Ocean using Forge for my client to see my progress. I pushed my latest changes to GitHub before my attempt. Then I added a .end.testing.php file to the project using Forge's settings and pushed that in another commit. Lastly I pushed another commit to try to trigger Forge's auto-deploy.

Unable to get DO/Forge to work, I went back to the local environment to get back to work and when I refreshed my local environment, I got the White Screen. I checked the php log and it had no errors and the developer's console in Chrome just gives me a 500 error (not very helpful). I am not getting the helpful Laravel error messaging.

Thinking I knew enough GIT to recover, I ran 'git log' and then git reset --hard af2f7569e3 which should have rolled back the last commit named "Initial Commit to Forge." Still White Screen. I ran git reset --hard 4e9ab0af5c8078 which was the commit BEFORE I even thought about Forge named "Preparing for testing domain" on GitHub -- this should have erased that .env.testing.php file. Still White Screen.

Totally panicking, I commented out EVERYTHING in routes.php and added the following to try to get SOMETHING on the screen but it is still blank:

Route::get('/', function()
{
    return 'Hello World';
});

What else could I try to recover my main work project?

Thanks in advance!
