You're off in your own, sullen little world today. Interactions with a friend or a coworker will leave you feeling even more moody and grumpy, because things just seem off. People are saying things that get right under your skin and irritate, and you're sniping right back at them without even realizing it.
This is more of a nuisance than a true problem. It's hard, but try not to take things personally that aren't meant that way, and don't let things get under your skin. You could feel oversensitive to anything others say to you, or the things they don't say. If you need a sounding board to figure out whether you're just being sensitive, ask a close, trusted friend -- and don't let their honest answer hurt your feelings! Arguments are more likely now than usual, so don't give in to the temptation. Try as hard as you can to hold yourself back from snapping at someone, especially someone like your boss. You don't want to burn any bridges for no good reason, after all. And most of all, don't worry; this transit blows through fast, and in a day or so you'll be feeling like a normal, functioning part of the world again, instead of off in your own private space.
