In a port, when a cargo ship is being loaded, there's an officer (usually, a second captain) who's responsible for "towing and loading". You have the same in your company, it's called a manager.

At this time, you're overloaded. The ship might sink. Please refer to the officer.

Document your workload, time-consuming tasks, and let them prioritize what has to be.

You ask for experience? I've been overloaded. More than once. Tried and did my best, worked harder and longer. Couldn't fulfill all assignements. Talked to my manager, and he realized I was overloaded, so they lightened the burden. Now, anytime I feel like being overloaded soon, I stop and reorganize my duties. The Eisenhower matrix helps you decide on and prioritize tasks by urgency and importance, sorting out less urgent and important tasks which you should either delegate or not do at all.

This is where talking to your manager helps.
