Hi
Consult a dermatologist and explain about tan not going after swimming. If the tan is making you feel anxious consult a psychologist. Being anxious about tan not going away could indicate that you might have health anxiety.
Consult a dermatologist first to rule out medical causes and then consult a psychologist. A psychologist will help you with stress management techniques to feel calm.
Next Steps
Consult a dermatologist first and then a psychologist
