I have a monstrous headache at the moment. I'm too awake to go to sleep yet, but I'm in too much pain to be thinking clearly. So take my comments with a huge grain of salt. I'm going to throw some ideas out. It they connect, great. If they don't, discard them.
I am going to guess that part of your "problem" may be high intelligence. No matter how many indications are in a birth chart that suggest that a person might be gregarious or outgoing, I believe that intelligence alone is enough to negate a lot of that. Why? Because it is more difficult to connect with a large group of people if you are above the norm. The younger you are, the more likely it would be that you would have been seens as a bit weird, not okay, an outsider simply because you were not thinking like everyone else. For instance, I often think that people of very average intelligence and limited imagination equate different (meaning originality, not being part of the herd) with being weird. When people suggest that I am weird because I have a brain and use it, I'm often tempted to say, "Thank you for the compliment."
I notice that you have almost no water in your chart. Only Pluto is in a water sign. Even your part of fortune is in Sag, although your North Node is in Pisces.
Is it easy for you to feel what other people are feeling, to tune into the emotions of other people successfully? Or is this difficult for you? Are you often suprised totally by what people are feeling, especially about you? Lack of water can indicate a difficulty in this area. You chart is almost totally air and fire.
At the time you were born, Uranus and Saturn were conjunct. I can't help but wonder just what happened at that time to "stamp" people born when you were born (in that short time period) in a way that reflects what I think that means. I can't think of two planets that are usually viewed in a more opposite way. Saturn is grounded and is generally linked to conservatism. Uranus is so opposite in nature, in my view. Yet these two energies are fused together, which is quite a paradox.
Some of the people I've met with this conjunction are especially good at approaching something normally considered very forward-thinking, even lacking in limitations (Uranus) and supplying a conservative twist to the whole thing. Or the opposite, starting out with something normally very conservative, but giving it an "out-of-the-box" twist.
This conjunctions squares your Sun and trines your Moon, so I think it is important. Also, has been mentioned, Mars opposes your Sun. In spite of your Aries Ascendant (which I think is more independent than social, by itself), Mars in Aries is in the 12th house. Anything in the 12th house is hard to get a grip on. It's hidden. Since the 12th is the house of hidden enemies, often planets there are our own hidden enemies until we do a great deal of soul-searching about what they mean there. With Mars there, you may not have a good understanding (yet) of what motivates you, and this may be puzzling to people you meet. I also think that 12th house people, and even with just Mars there, I'd think this way in your case, tend to look for more intimate and private relationships, usually preferring one-on-one "socializing" to groups. Not a blanket statement, but a definite tendency.
So let me stop there, with a little different view. If I am right about any of the above, please let me know. If I've blown it, be just as direct. I LOATHE readings that are so vague that they could describe anyone, so when I make some intuitive statements, I tend to let it "all hang out".
Finally, I hope that you are in some kind of department or "school within a school" that will allow you to meet other intense people that share your exact major or primary subject. If you are in a large university, for instance, and if you are just taking basic studies courses, you could easily get lost in something that is much too unfocused. Years ago I was very lucky. I went to a large university, but I was a part of the music school within that university, giving me a small and intense sub-group in which I could make friends in a more intimate setting.
