When you feel overwhelmed at work, it's important to take a step back and assess the situation. Prioritize your tasks, break them down into smaller, more manageable parts, and create a to-do list. Communicate with your manager or colleagues about your workload and see if there are any tasks that can be delegated or postponed. Take regular breaks, practice self-care, and consider techniques like deep breathing or mindfulness to help manage stress. Remember that it's okay to ask for help when needed and that taking care of your well-being is important for your overall productivity.
