Apparent ruin. Hysteria. Great pain.
It takes only one sword to kill: ten is way over-the-top! The scene here is so extreme that it indicates hysteria: an over-reaction to some problem.
The sky is clearing in the distance (unlike with The Nine of Swords): the black clouds give way to sunshine. Things are not as black as they seem.
The Ten of Swords is similar to Death in The Major Arcana. It indicates a difficult experience - a sudden and unexpected failure, disaster, or betrayal - being crushed by a power beyond your control - or else an ending, loss, pain, or release. You may be left hurt, shocked, feeling victimised.
However, the darkest hour is just before dawn - the trouble will soon be over, as this is a final ordeal, and the sun will soon rise again.
Ultimately the Ten of Swords brings hope, a new beginning, a rebirth, a rejuvenation of the spirit. This is an opportunity to reflect, and to learn from the experience. There is a purpose behind the pain.
Let go, and accept your situation. The change is necessary, so allow it to happen.
Reversed: The hysteria is seen for what it is. Or else, temporary relief from the pain, but a real practical or mental change is needed to bring permanent relief, otherwise the situation will revert to what it was.
