Sounds like a bad day. Maybe it's best to leave the energy drinks alone. Coworkers can be a pain. I had some trouble with some of my co-workers today too. I wonder if there is anything you can delegate to any of your co-workers, or are they not qualified to help you. It still sounds to me like you have too much workload. When one person is expected to do the work of 3 people it is a recipe for stress. I truly hope something gets better for you. Best of wishes. I know what it is like to have too much stuff to do.
