Hello,
The social anxiety part of it, besides the emotional problems while growing up, can be seen through the ruler of the 11th house (society/ friendships), which is the Moon. Moon is not well-placed in Aquarius (aloof and 'does not fit' in groups really). This effect is further heightened by its conj to Sat. Moon (emotional well-being) sort of feels 'left out' when amongst others.
That said, others (7th house) and your relationships are important to you, just as family is (ruler of 7th and 4th) in the 1st house (that what is important to the 'self'). However, benevolent Jup in the 1st (self) urges the self (so native of the chart) to be forgiving towards others. With Jup ruling Ven and the IC, and Ven so close to the IC (family and family roots), the forgiveness is more towards the immediate family (parents and siblings). This is your first step towards 'spirituality' (Nep-Jup with Nep in the 4th). Also, with Ven in the 3rd, and approaching the IC, relationships begin at home.
Sat square the Sun may show not only an emotionally distant 'figure of authority' (often father), but also a held-back (Sat) personality (Sun).
One more thing, Sat rules the 5th house (fun, etc) and is placed in the 5th, thus sort of doubling its influence. This may show that you may sort of feel guilt (or just haven't really learnt) to have fun. You might even make a strict parent yourself. A question for you: you have touched on the problems with the most dominating female figure in one's life, often the mother, but do you, in general, get along with females otherwise?
By the way, I don't know if you have realised, but you like to 'travel' in your mind, perhaps even otherwise.
