I feel like I've been gaslit into running FOSS but every success only brings me closer to fighting god
May I recommend Proton Mail? I used gmail for years then decided to finally switch and it was easier than I thought, tho tbf I also don't have a lot of people who need to email me, it was mostly services where it's easier to tell them to switch over to the other mail.
EDIT: I read your later comment nvm
