No Me Gusta

I totally need to go to sleep, but I wanted to write about something first. I emailed my boss earlier tonight to express how uncomfortable I feel about something I'm being asked to do at work. Do you ever feel like you're in an ethical/moral spot that you don't want to be in? It's probably not as big of a deal as I'm making it (I'm good at making things way more than they need to be), but I hate feeling guilty about things, and I'm pretty good at agonizing over things that I don't think are right. Meanwhile, I'm probably really annoying my boss - and perhaps another colleague or two. What he will reply and what I will do in the end remain to be seen, but it should be resolved one way or the other pretty soon - which would be great because I've been waking up in a panic over the situation some mornings recently.
