Not a big follower of shondo, just now heard about her mom. But jeez, reading all this stuff and her situation is giving me flashbacks. I've had a very similar situation when I was growing up and all the fallout that had to be dealt with over the years with being a teenager and becoming an adult.
I really sympathize with her younger siblings, but I honestly can't take stuff like this anymore. I prefer to ignore all of this since it has no bearing in my life.
But holy crap. That really sucks. The whole situation is terrible. It's definitely salvageable, but those scars are lifelong and no amount of meds or therapy will help with that.
A change in circumstances and time is really the only hope they have.
