What should I do....

...that's the qestion that always in my mind lately. Should I turn back? Or should I go on? Should I keep it? Or should I lose it?

This week has been a very hard week for me. Every choice I've chosen, Everything I've done seem to be wrong. And even if I could return the time, I still don't know what should I do? Should I choose the same choice? Or should I change it?
