It's true loathing and sick feeling you get when those small things at work get to you, which in now way directly related to work, but you can't avoid them due to the people (their actions) around you, the work relationships and the work context... Well, they'll never cease pestering you for those small things - it's their job.
Don't bother those pestering non-issues. Focus on issues. You gotta do your job, so get thick skinned. Don't sweat the small stuff at work.
