From what I can understand, it's probably has something to do with not trusting your instincts because your instincts have failed you before, I'd say that this kind of situation that you are talking about OP has probably have something to do less with hindsight and I don't think it helps that you think what you do is foolish, instead learn from that mistake, you know, find what you did wrong and try a different approach than last time, trading is a continuous trial and error until you get the right blend. Another thing that you can do is stop getting scared, your money will come back in some way in the future, with carefulness and courage to do trades with risky outcomes, I'm sure that your chances for profits are going to get much better than last time. @Text is right, it's all about your mindset, keeping your head in the game and not doing half-hearted decisions is probably the way to go.
