If I were you, I will stop trading at least for a moment, refresh and cold my mind for a while, and let my regret and bad experiences aside.
And I will continue by analyzing and thinking why I was always lost and lost again so much in trading with the previous strategy. There must be something wrong.
I agree with your idea. Don't be too hurry to trade more if someone is not really confident. OP really experienced bad results in his trading, he must feel deep regret. In this situation, stop a moment to evaluate and calm his mind are the best options. OP needs to know what is wrong in his trading way, then he must fix it. If he doesn't evaluate it, he will experience the same situation as before. But to evaluate properly and carefully, OP needs to calm his mind first.
