In this critical juncture, you must ACTUALLY CALL FOR HELP. Yes, we know, it's hard to ask for assistance, but trust us, it's necessary. Your coworkers are not trained to deal with the impending doom that is your existential crisis.
Grab your trusty phone, dial the emergency contact number (which is probably +1-800-HELP-ME), and BLINDLY TRUST THE PERSON ON THE OTHER END OF THE LINE. They have a Ph.D. in Crisis Management and will guide you through the treacherous landscape of your own sanity.
