"You can’t expect the world to just come in and swoop in and save you and make it all better again" - Tara Tara and her brother Gavin grew up surrounded by drugs and violence. Today, their lives have gone in quite different directions. Tara struggles with addiction to alcohol and prescription drugs and is trying to get it under control. She’s put her university studies into sociology on hold to care for her sick father. She credits her fiancé Ben with helping turn her life around. "You can’t be a victim anymore of your circumstance, you are the only person that can change your life," she says. Gavin is a recovering ice addict who struggles with anxiety. He recently found out he probably has drug-induced brain damage, which he says gives him a reason for missing appointments and commitments. "My memory is really bad from smoking too much," he says. "I can sort of have a bit of leeway." Gavin says he’s doing his best to fix his problems. But Tara says he doesn’t take responsibility and worries he will use his cognitive impairment as a crutch. This week, Insight asks, where does personal responsibility begin and end?
