Wherever you are, whatever you do, you are always going to be YOU. Even if you change your outer identity, the ‘inner you’ is never gonna disappear. Your memories of your life are your own. No one can take them away from you.
So, instead of feeling desperate and depressed, go back into your past, dig up the happy moments of your life, with the people you love and realize how blessed you are.
Once you move your attention from the ugly picture of life to the beautiful one, only then you will be able to SURVIVE.
