Work avoiding again

This is stupid. I'm turning into someone I'm not. Or at least I hope I am not. I don't normally swear and get angry over nothing, or bad mouth people. This is (I am told by somebody that has received emails from person that doesn't want to know me anymore) supposed to make me a better christian, and to help me to not sin. It is actually just turning me into an angry spiteful person whose 'patience with other people' thimble overflows if I even just see the person, or someone mentions them, with the result that I flip out at others. How is that helping?
