Accept the loss and take a rest for a while because at that moment, you will have a big sadness and it needs to calm down. And if you can calm down and think clearly, you can continue trading to recover your losses. Before you can calm down, I suggest you not try trading because that can attract you to get more losses without you realize. Besides that, you can gamble with your money as you can not analyze because your intention to recover your losses becomes bigger, making it difficult to recover the losses.
