Try as you might, you can't seem to keep your focus on anything. Your thoughts all seem to fly right out the window, especially when you're trying to talk to someone! Somehow the boundaries between you and the other person seem to meld and merge, and all of a sudden you feel like you're in their shoes, which makes it really difficult to express your own point of view.
Therefore, this is not a good week to try to have a serious conversation with anyone. You're not expressing yourself as well as you usually do, and misunderstandings could very easily arise, on your side or theirs. Since you're not feeling particularly energetic or strong, others perceive weakness in you and might try to take advantage. It's also possible that you could see or hear an offer that seems too good to be true, and since your usual filters aren't working so well, you might actually fall for a fly-by-night scheme -- which you'll regret when you find out all the facts at a later time. So, forewarned is forearmed. Don't be too hard on yourself this week, and next week you'll feel a lot better.
