to harass or treat roughly with or as continual biting or tearing with the teeth*

I worry. A lot. About things that I can't even control just because it gives me something to do. For example, lately I have an ongoing inner dialogue of conversations that have yet to occur. Yes, it is good to think before you speak, but even I think this is overkill. Right now... I am worrying about work this week. I will be the lead person in the lab during a period of heavy activity. I already have everything set-up for tomorrow (of course) but I am worrying about mistakes and screw-ups that may or may not happen. I am worried that someone is going to want me to do a shipment and I won't be able to do it. I'm worried that the crap is going to hit the fan and I'll be the one that everyone looks to for an explanation. I'm worried about not being prepared enough to handle the volume of work in a short time frame. I worry because I think that if I don't then it seems like I don't care about my work. Maybe that is just what I perceive as what others think of me. (I should have taken that Behavioral Psych course in college)

* This is the first definition of worry listed in Webster's. Interesting.
** I plan on coming back to this and completing my thoughts/discussion; I'm just overwhelmed now and I drank too much sweet tea while typing this post.
