Getting emotional for your money is normal but minding it for so long isn't. Getting rid of your emotions while trading might broke you. The right way to manage it is to control it example trading dedicate yourself into giving you heart and mind to pick the best suited for you being emotional on your loss won't give you knowledge instead learn from your mistakes and strong dedicate yourself from learning and soon controling your emotions will be natural.
That is true we cannot take away the fact of being emotional because that is one thing that makes us human we have emotions but of course over reacting into something is not a normal thing so it is a matter of self discipline because maybe in your childhood days you've been raised like that and now you are adapting that attitude into your work then I am saying that act like a man or be matured because minding the business problem for so long is for kids. Mind for a solution to the problem much longer dude.
