I hate to say this, but after listening to Heather and hearing her say that she didn't feel she needed counseling like the rest of the family because she feels she can pray, I feel like she is seriously in denial. My heart goes out to this family, but in all honesty when it finally hits Heather its going to hit her hard I'm afraid.
Joran van der Sloot refused therapy and he murdered again. Amanda Knox refused therapy and she just published a book. Therapy isn't always the best choice ... but in some cases, it's necessary. Having a strong belief in God can quite possibly replace any need for traditional therapy.
