I wish you hadn't deleted them, I would have liked to have read your comments.
vannasan, I have Mercury in 1st square MC too, and I have never had any problem with public speaking. Your question sent me on a quest today, and in addition to waybread and miquar's interpretations (both very good as usual!) I'd like to offer a newbie's idea...yours is a nighttime chart, and that puts both your Sun and Jupiter naturally out of sect (they are happier in the daytime.) This might make you a bit less extroverted overall. Mostly I was looking at your Mercury in Capricorn, which is ruled by Saturn in Sagittarius, the place of Mercury's detriment. So even though Mercury is not in bad shape, my supposition is that his ruler being both in aversion (unable to see him) and in the place of his detriment might make it difficult to express yourself publicly. With Libra on the MC, this is the place of Saturn's exaltation, and the domicile of Venus...who is also in Capricorn with Mecury. Venus rules many things, among them the arts (and actors? or public speakers?) but again with a nighttime chart, the triplicity ruler is Mercury (and we already looked at his issues with Saturn) and your MC then will disposit back to Venus in Capricorn...ruled by Saturn. So my newly learning guess is that it is Saturn that is making it difficult for you to be at ease with public speaking. I wonder though, since your MC is in Libra (the exaltation of Saturn) if after your Saturn return you might find talking in front of a group easier...
