I agree that they need help, and apparently they are getting it.
Most psychologists/psychiatrists would suggest a person remove themselves from the toxic environment that is causing the distress, but how can the a's do that?
This is in their face every single day. not only are they dealing with a murdered grandchild, but their own daughter is the accused. They have media fighting to get the latest scoop, people who falsly appear as friends who betray them, people have sent them death threats, 'bloggers' analyzing their every action or comment, the trial looming, and people deliberately trying to bait them into an angry state, for their own personal gain.
Its no wonder that they are still not coping. Dealing with everything else takes time away from the healing process.
