I don't know how to explain. It is so frustrating. I have always a feeling that someone would like to abuse of me. I mean it psycologically. It is a strange feeling and you don't have it (as I understood, you don't own the square in your chart). We just can't let someone to control us...it is like an obsession, we fear it. Our individuality is so important. Better lonely than...
I actually thought, that the square can bring low self esteem as a bed side of Pluto planet and this brings a person to fight it's own ghosts. Probably we reflect outside, towards the others, our inner world. As you said, we are our own enemies, not the others, but we feel it with distorction. Pluto means underworld: besty instincts, hate, obsessions, power, deep crises. But also insoddisfaction and a need to change, to destroy ourselves to rebild from 0. Nothing is certain with Pluto. The Sun is so ful of itself and so certain, where Pluto always put a lot of question-marks, doubts about averything.
i see sun pluto pluto aspects or transits as gifts to move on, learn a thing lr two, pluto transits give you lots of time to figure them out x also u see pluto transits and experiences leave u with an option to say bugger off, saturn transits dont
eta hecate no one has the right to abuse you but u have the power to stop them doing so, use the power, cut them off
