The Moon is in Cancer this morning, opposing Saturn and Pluto in Capricorn. Whatever stress this might cause should be intimately familiar.
If that's too vague, just think in terms of family patterns. Does the person you're pitted against remind you of your mother, your father, a brother or sister? The DNA testing people do these days reveals the intricate differences and similarities between siblings or cousins or whoever. You can't deny it.
One point here, the Moon and Saturn are in their home signs. This goes a long way towards easing things. Parents are often horrified at what their kids do... right up until they recall what they did at that age. Pluto in Capricorn does dig up some uncomfortable stuff. It's kind of funny, not funny, but it's also real.
