Peterborough City Hospital in Cambridgeshire has launched an appeal on behalf of this man.
The last few weeks have been truly horrible. I go through so many different emotions. At times I am angry, frustrated, depressed, lost, and confused.I just need to find out my name and I hope someone out there will recognise me and help.
Doctors say they have tried everything to help him regain his memory.
Anyone with information has been asked to contact the Cambridge and Peterborough NHS Foundation Trust on 01733 776014 between 8am and 8pm.
