As a diagnosis I don't know if it shows/what could show it, but as a personality characteristic I guess it could be related to a couple of things:
1.Most of your planets are in the eastern hemisphere, that is you don't seem to be so others-oriented.
2. Your capricorn sun could have a say in being more of a loner, I've noticed that in the capricorns I know, not that you can't be friendly or not want to connect to people, but you seem to be more closed and independent.
3. The aquarius ascendant with moon in aquarius can make you more spaced-out, and a loner at heart, you just need your freedom and time alone.
Hope it helps
