If one day I lost my memory

What if one day I lost my memory? I would lose the my sense of security. Maybe my parents and my friends would tell me what my name is, what I have done, etc. but I would just lose my courage to trust them. I would felt feel desperate about anything everything around me, because I couldn't remembered the people I loved ever, as if I have never lived. How terrible! So, maybe I would choose another a different way to live, travelling to another country, speaking another language, or meeting another some different people. I couldn't accepted to reading the sad expressions on the faces of the person people who knew me, on the country in another country, I would choose to see the smiles on strangers.
If I lost my memory, I don't know if anyone could help me to find the lost memory it. I would always be myself, but who can could tell me who I am?
