with my humble opinion about your emotion I think you should first of all build up your emotion before going in for trade because that's what can help you stay long on trading.
about your loses I guess you should take a weekly review and see what you failed and try putting them in other and make corrections.
Traders need to learn how to control their emotions because this is one of the ways we could end up losing big because the confident to enter the market is not there. We need to be relaxed and focus on trade we want to buy or sell.
Emotions with a proper control can make traders to keep losing trades because their instincts do tell them not trade confidently. Once a trader is able to work on his emotions, one thing solved ana and bette luck will starts coming which could increase the chances of making consistent profits as trader. Greed can be a result of emotional pessimism especially when a trader think the trade he is about to take might end up in losses because of other people's experiences or what he had seen so far.
