8 of swords is not the most happy card to receive. Except when it is placed in the past as something you have left or about to leave behind. 8 of sword means anxiety, worry or fear of something. One is completely up in one's mind. Hard to let go of something. 8 means movement however. which means that no matter what, this will pass into what is to come. New worries with it, which is why it is incredibly unnecessary to end up in 8 of swords.
But how do you not worry and think negatively? There is only one way and that is to think of something you want to happen, something positive.
Thoughts are difficult to remove but easy to convert. So where do you want to be? How do you want to feel? Think it, feel it and be it.
