The first thing you need to do is to stop trading on the minute charts. The higher the time interval, the stronger the signal, the more time you have to take a decision, the less you need to follow the price. Psychologically, it is easier to trade on the larger timeframes.
Secondly, apply Money Management. The more you risk, the more dependent you become emotionally. If you do not risk 50% of your capital in one transaction when you have opened the minimum lot size, then you should not really care how unprofitable or profitable your trade is. When at stake there are larger sums, immediately your big problems begin. All your mistakes would definitely go away if you start observing the rules of money management.
