It's great that this person seems to be helping you and willing to step in.  It's so much for you to handle alone, so hopefully this person continues to take a bit of that strain off of you.

I don't know if this helps at all.  Probably not.  But does it help to think of the 17 years of abuse you suffered through from this person, as it happened in the past and reliving it in court doesn't change anything in the now?  I know the prospect of reliving it, and even just telling people all about it must be terrifying, but keeping yourself in the present while doing it may help a little.  Possibly.  Maybe you could talk to this person about some advice on how to get through it, or if there any options for making it easier on you.  Surely there's some things they can do.  I'm sure a lot of people are confronted with having to relive a lot of trauma in court in from of their abuser, so you'd think there would be  some ways they make it a bit easier.  Like I said, I have no idea.  Just some random thoughts.

I'm sure i will enjoy the catch up with my sister.  She's the only biological relative i know know who still talks to me, so it means such a lot to me.

Since you asked so nicely... here's some interesting astronomy facts...

• Neutron stars are insanely dense – A teaspoon of one would weight more than Mount Everest!
• Black holes can ‘spaghettify’ You – If you fell into a black hole feet first, your feet end would be pulled by gravity so much more than your head end that you would be spaghettified.
• There are more stars than grains of sand on all the beaches on Earth
• Jupiter's red spot is a storm that's been going for 300 years.
• Light from the sun takes 8 minutes to reach the Earth
• Earth moved through space at 828,000km/h - when you factor our orbit around the Sun, the Sun’s orbit around the Milky Way, and the galaxy’s movement through the universe.
