Looking at some of your placements, I'm honestly surprised you'd make such a remark that you care more about broader humanity than individuals. I have the same sun sign as you and an Aquarius moon, but I can't seem to relate to the humanitarian spirit of Aquarius. Maybe it's because it's in the house of Taurus, a much more down-to-earth sign. I am a rebel in the sense that I often refuse to follow conventions blindly, and I'm not easily swayed by the emotions of a group, but then my Cancer sun makes me an emotional and family-oriented person at heart. It can be a battle, no kidding, and I'm still trying to find that equilibrium. If I had to choose to let one sign's qualities triumph over the other, I'd definitely choose Cancer. I don't think it's hard for me to relate to people on a superficial level, but knowing me on a deeper level requires much more time especially when sometimes I don't even know myself very well. I sense that deep down you crave closeness and affection, but it takes quite a while for you to show it unless you're really sure. Virgo can be quite analytical, so you'll really be examining everything about the other person.
You have Moon in Virgo, which makes you shy, reserved, a perfectionist that doesn't just open up to anyone unless you think they've met your expectations, and those expectations, as you've mentioned, tend to be high. Your Sun and Mercury are both in the house of Aquarius, which gives them Aquarian tendencies as reflected by your love for greater humanity. Your Moon and Mercury are sextile each other, which means once you open up to someone it's not hard at all to communicate how you feel. Mercury in Cancer gives you a subjective, moody way of thinking that's all about closing the distance. The Moon conjunct Mars means you can get quite passionate, and being in Virgo you can be overly perfectionist and critical at times, which may put pressure on some people. Your Mercury's in opposition to Neptune and Pluto, which means you are likely someone who has an idealistic, perhaps overly active mind, but you might be prone to a lack of realism at times. I have heard that a personal planet aspecting Neptune gives one the desire to connect to something greater than themselves. However, due to your hard Mecury-Uranus and Mercury-Neptune contacts, when your expectations and reality don't match, you get deeply disappointed and start doubting just about everything in life. Your sun is trine Pluto, which means you likely give off a very intense vibe, everything tied to your core identity and the emotions that govern it are intensified. Combining that with Sun in the 11th house, you are indeed looking for a deep, soulful connection in all of your friendships.
I'm a noob at reading birth charts, but I think the reason why you're so detached right now is a combination of Sun and Mercury in the house of Aquarius plus the fact that you don't share yourself easily. Maybe you just need to meet the right people who can connect with you not at a shallow or superficial level, but someone who can really get inside you. And that, unfortunately, is becoming harder and harder to find.
