The LEAST appropriate way to proceed is to coach her how to quit the job in a professional manner. This would imply that she is not capable of working in that environment and that there are no other options to help her succeed. It would also undermine her self-confidence and career goals. A better approach would be to explore the possible accommodations and supports that could make her job more manageable and enjoyable. You could also visit her office and identify how she can create more order in her workload, such as prioritizing tasks, using a planner, or delegating responsibilities. You could also talk to her support team about ways to cope with her anxiety, such as relaxation techniques, counseling, or medication. References:
