You came looking for the aspect that explains why your mind fights you. It exists. It is not this one.
What it looks like in a life
What people usually have when they search for this is Mercury in the sign just after or just before their Sun, which does read as tension. A Leo Sun with a Virgo Mercury wants to be generous and thinks in corrections. The real square is elsewhere: Mercury square the Moon, Mars, or Saturn is the aspect that sets your thinking against the rest of you.
The gift
Ruling this one out is worth something. It narrows the search and stops you from explaining yourself with a pattern that is not in your chart.
The friction
Weak chart software prints impossible aspects, and people build an identity on them. Check the degrees before you accept any reading.
The esoteric layer
Classical astrology worked from what the sky actually does. Mercury's tight orbit was known, and no lineage assigned meaning to an angle the planet cannot reach.
Where this goes
Look at what else your Mercury touches, because that is where the friction really lives. A full natal reading maps every aspect it genuinely makes.
