Emails stopped coming in 4 days ago

For 4 days now i have been trying to get my emails to start working again & i have tried contacting help, looking at the help forum, leaving feedback & apparently it is impossible to get some help into why my emails stopped coming in. Im assuming my inbox needs to be cleared out but the “mark all” option is no longer in gmail & i need to delete 200,000 emails. I didnt know my account would just stop cuz i never deleted any, a little help would be nice. Im missing important emails. A heads up email or info that this would happen would have been nice. Im not happy about this. Its taking up hours of my time deleting emails one by one. Ugh
