Hey, I have Moon-square-Saturn. It's part of a T-square with Neptune. It hasn't exactly been a ball of laughs but I don't think it's quite as bad as you make out. I mean sure we were really poor when I was young and my parents are rather severe and strict but to the best of their ability they (and everyone else) spoilt and protected me (OK, that was probably more to do with Jupiter in 4th house and Jupiter-trine-Venus and Venus-trine-Mars more than anything else). And one could say it is the expectations of my parents which pushed me into becoming such an overachiever. Mars conjunct Jupiter probably helped there too though. OTOH I do have Jupiter-square-Sun and it's much tighter (about an orb of 2) than the Moon-square-Saturn which has an orb of about 7.
Ah, excessive pessimism and excessive optimism together. Hey, it all balances out in the end
Hmm...no wonder I seem to bounce between the two extremes. But fortunately the optimism is stronger
Anyway, the point is, other elements of the chart can help alleviate bad aspects, even horrible ones like a Moon-Saturn-Neptune T-square. So you can't predict things based on a single aspect but have to look at a whole chart.
If you just look at the Moon-square-Saturn you might say that my parents were very strict, severe, and childhood was tough. Which it was, in many ways. However there are other elements of the chart which lead to a lot of cossetting. Which is also true. In fact it may be that the Moon-square-Saturn would be a fortunate thing for me in the end as without it, my natural excessive optimism (Jupiter-square-Sun) and tendency to be spoilt because of the charm from (Venus-trine-Mars and Venus-trine-Jupiter) might go way overboard. One could say in the end it provides a balance to the other parts of my chart. I think the Moon-square-Saturn helped push me into being an overachiever. Also it, along with the fact that Venus is in Capricorn helps steady my somewhat fickle emotions (Sag Sun, Moon in Gemini, 1st house - fickleness and changeability are in my character. Venus trine Mars isn't exactly known for its steadiness either).
Another example of how other elements in your chart can help alleviate the problematic aspects is you call Moon-square-Saturn the orphan's aspect. I was very nearly abandoned by my parents as a baby due to political considerations and poverty in my home country. However, some fortunate strokes of luck (Sun-square-Jupiter, Venus-trine-Jupiter, maybe even Sun conjunct PoF I guess) led to me not only being not abandoned by brought to a developed country where my life is magnitudes better than it would have been in my home country. Now, thanks to the hard labour of my parents and my own I live in a very comfortable middle-class lifestyle when I was born in poverty and danger. And as I said, it is possible the suffering from the Moon-Saturn-Neptune helped provide me with a sense of perspective and seriousness to balance the other parts of my chart.
