AppLeo, With Mars ruling your 11th house from the 7th house of open enemies, I think you expressed that when you wrote:
You do seem to see other people as the enemy. It's not that you feel badly around other people: but "they" actively make you feel that way. "They" actively abuse your time and energy.
And you're the passive recipient of this, right?
Saturn square sun can confer real issues with self-esteem. The wounded lion retreats to his solitary den to lick his wounds.
Maybe it's time to take responsibility for your part of the equation. People can't just make you feel rotten without your permission.
But beyond that, maybe you're just cut out to be a loner. 8th house people tend to be very private.
The question is, what exactly do you want?
I agree with this, I think. There seems to be quite the spiritual ride promised in the natal chart. Sun in aspect with generationals, in the 8th with Moon in the 9th, also aspecting a generational planet.
Some people write the generationals off but I believe it's because they don't even understand them. They're the most complex. Either way, the main focus of the native seems to be to find transformation. There is light and good will in the Sun in Leo, and his mission in life is to dig deep within and find meaning in all of his trauma so he can be reborn. There is definitely capacity to make it happen (since Sun trines Pluto).
I think planets conjunct to the angles are usually the easiest to spot because they tend to show easily observable events. With Mars in Cancer conjunct the Descendant there, it seems to me like there's a desire to actually connect with others.
I see the 7th house as the way we psychologically view ourselves when we confront others. OP might be serious with other people, considering his ruler is trining Saturn and squaring Pluto. He may view creative outlets as something that shield him from having to deal with others in general. Saturn is in the Moon's exaltation, after all.
To be honest, I'd really like to read this chart more deeply but I think it is hard as hell to understand what the cosmic charts tell us. I'm not a beginner but I'm no expert either. If we're gonna go down the generalization path then it's easy.. but once you know just how much you would need to know about astrology to be able to stop generalizing you just feel baffled and overwhelmed.
