Thank you Hexidecimal,

I'm glad someone who has gone through this replied to this. It's very rare to find someone that understands my sister's problem.

She was actually about to begin seeing a psycologist that also had the same problem a few years back. He totally understood the problem, and never even pressed trying to meet her in person. He sat in his car in our driveway talking to my sister with his cell phone. She was actually considering seeing him for the next session, but as fate would have it, I was a witness to a murder and we packed up and came to live in Mexico. It wasn't safe for us to continue living in California since the murderers knew who I was and where I lived.

It just wasn't her time to get better, I guess.
