The 9 of Swords is associated with Mars in Gemini (especially appropriate with the upcoming New Moon in Gemini conjunct Mars). This is the worry card. When it comes up, you're stewing over something. Not just stewing...you're obsessing. Going over and over and over the possibilities, guilt, etc. But this card means what you're worrying about is 95% in your head. There may be an actual issue, but you've made into something so huge that it doesn't even resemble the original issue. Your fear is much, much worse than reality.
When this card is reversed, it means you're already on the way up and out. You've found a way to deal with the obsessive worrying (or you will very shortly) and you're dumping that mental baggage.
This connects to Mars in Gemini's energy of aggressive thoughts, scattered into a whirlwind of conflicting choices. When Mars isn't focused, the result can be endless fluctuations that result in the thing that Gemini fears the most; a trap. This is a mind trap, ceaselessly whirring through possibilities, but never arriving at a conclusion.
