What is my character?

Should I  keep taking a tough line with subordinates or should I stop. Perhaps I have a (double) split personality. I am soft and gentle when getting along with friends and family, but I change at work. I don't know whether it is right. I don't know which one is the true me.
我想我本是温顺的小女孩????，只是工作慢慢把我磨砺成这个会凶人的女人????。每次和同事或是合作伙伴发完脾气我心里都会自责。为什么要这样对待别人，为什么不给别人再一次机会...可是经验告诉我如果我犯了错别人不会放弃谴责，别人也不会在给我第二次机会。每个人都会变的，也不是每个人都能按照自己想成为的样子去生活。
ps: today, I begin to pardon Yang.

Hello Amanda,

I think you need different personalities at work and at home otherwise some people at work may take advantage of you. If a person can be one of two types we often say that they have a 'split personality'. Apart from that there are just a few small mistakes.

Hope this helps
