The Nine of Swords symbolizes past fears, traumas, and anxieties.
When pulled upright, the Nine of Swords is associated with past fears, traumas, and anxieties. This card especially plays upon fear and anxieties, and maybe even traumas, that have already happened. It leads these fears into the destructive part of your mind and plays them on repeat. It's a nightmare of a situation, and one you're ready to escape as soon as you can. You are haunted by this card, and the circumstances that surround it.
Unfortunately, pulling the Nine of Swords reversed isn't much better than pulling it upright. It means that you're still feeling trapped in the nightmare of your thoughts, fears, and traumas, but that you're ready to escape this situation. However, escaping this situation is going to take some work on your part, but you're ready to put in the work to leave these festering thoughts behind. If you don't put in the work, you could fall deeper into your destructive mind.
The Nine of Swords is telling you that you need to put in the work to escape the destructive center of your thoughts, or fall deeper into them.
