You failing is part of your investors business model. They've moved on, they no longer care.

This sounds like a negative statement, but it actually has extremely positive repercussion: you no longer have to worry about them AND you have a few months to do whatever you want. Anything. Have fun and enjoy it. Maybe build something cool, completely new, something that you want to see exist in the world. And you never know, just letting go of the burden, accepting that what's done is done, and enjoying creating something for fun may actually lead to something.
