The Nine of Swords is the card of nightmares and fear, and seems to have a negative'feel‘ to it. However, the troubles in the Nine of Swords are primarily of a psychological nature and do not necessarily indicate suffering in your external reality. That is, it is your mind that is creating the fear and anxiety, not your actual circumstances.
The Nine of Swords can also suggest fear of the future. If you allow yourself to be constrained by fear of the future, you are at risk of eventually creating a negative reality for yourself because of your expectations. Thus, your nightmare becomes your self-fulfilling prophecy.
Generally, this card indicates that you are worrying too much about a situation. Literally, you are being kept up at night because you are so anxious about a particular issue.
Although most people experience frustration, fear and uncertainty at some point in their lives, you should not allow those negative emotions to freeze you or keep you from pursuing your goal. Expect at least some level of uncertainty in the future, and gather your inner strength to remain as flexible and adaptable to that uncertainty as possible.
The Nine of Swords can also indicate that you are being excessively hard on yourself or putting yourself down. For every mistake you make, you blame yourself and get angry at yourself for messing up again. So, when the Nine of Swords appears in a reading, ask yourself why you are being so hard on yourself? What can you do to make yourself feel better?
