Experiencing huge loss in trading, investing or gambling is a phenomenon that really hard to handle and recover.  The feeling of regret on your losses might eat you up and might ruined your confidence. When  I suffer a huge loss, the first thing I did is I entertain myself to forget my losses.  I also rest for a while until I accept everything that happen.  I also evaluate my move and my strategies I used why I fall into losses.  After evaluating my action, I right down the next strategy I might use so it will not happen again.  I do not even think to stop because I believe that the next trading, investing or gambling is a different story.  I also orient myself on the saying that Quitters never win so I must not quit to be able to win.
