I have always been this way and it drives me mad - I absolutely detest conflict of any kind and go out of my way to avoid it. But sometimes situations arise where conflict is inevitable.
Take my current situation. I run a small business and have a number of people who subcontract for me. I have given a lot of my time to supporting one particular person, and last week I discovered that she has been piggybacking off my business in order to build up her own (think - providing clients with her personal contact details in order to take future business away from my company). When I raised it with her I received a curt and dismissive response, not the apology I was expecting. I have arranged a call with her this week. She is in the wrong here and she should be the nervous one - but instead, I am here feeling tense, anxious and stressed about having to discuss the issue. I keep rehearsing what I will say over and over again until I drive myself insane. Why do I find this so difficult? I have every right to stand up for myself and the business I built from scratch - I wish I had more confidence with this sort of thing.
