I need to sleep now or something worse happens.....

I tried to install VM Workplace and install Ubuntu, but that didnt even work. I wanted to try to search it with their Linux tool.

The application: https://play.google.com/store/apps/details?id=de.schildbach.wallet&hl=de
The only "recovery" I can think of: https://github.com/bitcoin-wallet/bitcoin-wallet/blob/master/wallet/README.recover.md
I fear the Google Playstore Account from which I downloaded the wallet is lost forever, so I dont know what to do..........
