The only thing that comes to my mind when this happens is to remove your focus from gambling and focus in something else, whatever it is , just be different from gambling.
It works for me and if you don't change your focus there is no other way to change your mood, you will be sad and down.
Well said buddy, people should do something different whenever they are facing consecutive and huge loss and they should have a different mind-set, this problem happens very often because most people think they could easily make money from gambling and this is the real mistake that they ever did. Focusing on something different from gambling that requires technical analysis.
