please help

usually i don't ask for help on here, but i am losing my damn mind. i broke my phone enough to not be able to turn it on, had some important gmails on it, and googles "try another way" is just a big lie, literally cannot relog in. i just need to know how to even get my gmail back from that phone and googles "tips and help" just SUCKS, so please let me know how to, any damn way i don't care if i have to go to the damn moon and back to get it
