I deleted a Gmail adres I used through college, first I switched the emails of essential accounts like banking manually. Then I manually erased all histories and linked devices. Then follow the FAQ instructions to delete your account. Note it's only "deactivated" for 3 months untill login. Took me a solid 4 hours what was supposed to be lunch.
I love birds so much I often check the local crows and pigeons and a few other species. But pigeons are defenitely not the sharpest. They can be tamed though.
