Sorry to hear that you have to deal with those issues with your half-sister, that's a really tough road. We don't know what really did or didn't occur between Kim and Sarah and whether Kim was being truthful in her rant to Sarah or not. Regardless of whether Kim's rant was justified or not, it still should have been done in private. Cynthia Nixon has posted a picture of her and Sarah together. Seems like she is showing support, and so has the actor who played Samantha's boyfriend. That indicates to me that Kim may not be being truthful. I wouldn't be surprised if Kristin Davis decides to show some support too.
