If you are experiencing burnout, you may have diminished motivation; have more difficulty managing your emotions; have difficulties thinking, concentrating, and making decisions; have problems with sleep; and have physical complaints such as headaches, muscle tension, and gastrointestinal problems.
Anxiety is actually a very normal part of being human. It is a function of the brain whose purpose is to keep us safe and well. In small doses, it can also help motivate us to complete important tasks. Anxiety is a product of our sympathetic nervous system, a network of nerves that are responsible for our fight, flight or freeze response.
