Usually the 10 of swords represents some sort of metaphorical back-stabbing or betrayal via intellect or tongue.
Everything happens for a reason, I believe.
I don't know you or your situation but just based on my experience and knowledge of Tarot....A card like this could possibly mean a person (or people) in your life might be about to show their true colors, which is good because maybe you'll be better off without them.
Or maybe it could mean that some sort of idea/theory you've been working on will be shot down by the intellect of others working against you, which could be good because maybe now you'll have a clean slate for an even better idea.
Does that make any sense to your situation?
