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.
There is no such thing as building emotions. If you lose so much amount of money in trading, you will still get hurt no matter how much you think you've trained or built your emotions. The only way op can get hold of his emotions is by trading with amounts he can afford to lose, with this, even if he loses and still gets hurt, he would still be able to control himself not to take some impulsive decisions.
@op, losses is one thing traders cannot run away from, so you must take risks management seriously. Keep learning to improve your trading skills and with time you would get used to everything about trading, including losses.
