Are Cancerians truly over the top with moodiness?
The Moon rules your sign of Cancer, giving you a bit of an emotional streak. You can be temperamental when you don't get your way, or a tad diva-ish if someone crosses you.
Not that anyone's questioning your fabulousness. They just don't want to take the punishment. You can also blame yourself, and second guess things you've said and done.
Did you go too far? Being in touch with your emotions is one thing. Letting them rule your life is another. Best to get that temperamental streak under control before you lose a friend over it.
