Melle was reinstated to clinical duties in January following a private disciplinary meeting which ruled she will face no further action over the alleged breach.
She said the situation “should never have come to this”.
Melle added: “No nurse or other medical professionals should ever have to face what I have faced simply for telling the truth, doing their job, and reporting racist abuse and physical threats from a patient.”
She said on Monday that “the darkest days of my life and it is still far from over”.
Melle still faces ongoing investigations by the Nursing and Midwifery Council (NMC).
A spokesperson for Epsom and St Helier Hospitals NHS Trust said: “Racial abuse of our staff is never acceptable, nor is discussing a patient’s private medical information publicly.
“We are sorry that Miss Melle had this experience and we issued a written warning to this patient, but we expect all staff to maintain patient confidentiality at all times.”
The NMC has been approached for comment.
