I am not sure that Barrymore is the right person to "try" and help anyone and do not think he was being cruel to be kind I think he was just being cruel!
Jodie is sel-absorbed and doesnt like to see negatives about herself but that by no means makes her a bully it makes her narsasistic maybe but a bully
I agree she has issues that she needs to work through on leaving the house but dont think that they are imapcting too much on her time there. Other than she may well be struggling to cope the next day or two with the anniversary of her best friends murder being today.
