^I agree.
I like Belle's storyline at the moment. The writers are really focusing on the effect that all these traumatic events of the past year (supporting Aden through his hardships, being held hostage by Aden, her car accident, being threatened by the developers, being attacked by the developers, the school formal disaster etc.) have had on her. Like LAURZY! said, though it can be kind of annoying the reality is that the things that she's going through now like taking drugs, stressing out, and constantly ringing Aden for help and reassurance (and needing reassurance from other people like Geoff and Irene) are things that real people who have had PTSD do actually go through.
I think Jess is doing a fantastic job of portraying someone who feels like they are losing control of their life. I know some people think that Belle's being mean and some of her behaviour is out of character but, again that is what happens when someone thinks that they are losing control. They don't realise what effect their behaviour has on others. They are very focused on their own troubles. I hope that the writers continue to do this storyline justice.
