Wow...that sounds like an amazing experience...a whole island made of quartz! whew...amazing amazing...sounds like exactly what you needed (of course!).
I am well, too - I had craziness a few months ago also - and I'm feeling muuuuuuuch better now...phew...
Hey, did you notice that really good-feeling transit? It started in mid-July and will go until late August...but it peaked in the middle of that - it was/is Pluto squaring Jupiter. I've noticed that it has reeeally affected Scorpios and Sagittarians (pluto rules scorp and jupiter rules sag) or people with Scorp/Sag in their charts....and it made us all feel like we could do anything! A real expansive feeling....the feeling has been - we're going to transform, so we may as well transform into this positive, expansive, big-thinking/feeling benevolent being!! (it really felt like a think-big transit) I wonder if you went to your Greek Island during this period??
