Everytime I experience losses in trading, I calm myself by turning my attention into other things so that I cant think deeply the losses and the mistakes I did. When I was still new I cant handle losing my money and it makes me depress, however as time goes by I learned to accept the unfortunate situation and do better the next time. Because in the end I realized through that losses you will learn something. Its best to only use the amount you can afford to lose so it wont be hard to accept having losses.
