I would make a new one and carry on as if nothing ever happened. I have my email at my own domain for which I pay about $10/year, my phone runs LineageOS, and I back up all my important data between my various devices with Syncthing. I try my best to avoid giving up too much control over my life, especially when it's as easy as purchasing a domain, installing an operating system, or setting up an application. Altogether, these actions took about an hour or two to complete, and they'll likely save me so much more in the long run. If I can do it, you can too!
