I'm think I am going to blow up on my co-worker
Why are you going to blowing up on a coworker? Tell me more.
My brain keeps telling me bad things about her.
It's not right to yell at coworkers. You should try to settle your problems amicably.
Thanks. I'm just going to take a step back and give it some extra thought then.
Great! You will be happier mentally by rectifying the issue by being mature and rational about it. Sometimes bad blood is the result of misunderstanding, and all you needed to do was talk it out.
