Quotes from that Oprah interview:

When it started to come out, I thought I would go mad. Multiplicity keeps you sane under the worst conditions, but I actually though I was going crazy.

Oprah: That's so interesting, and I say this with all respect, because you think this is sane?

T.C.: Yeah. This is sane. This is sanity. I am sane. We are sane.

Oprah: See, I think the idea of having 92 different people living inside of me would make me a little crazy.

T.C.: Believe it or not, it's easy. It's easier to deal with than the abuse was.

Dr. Phillips [Truddi's therapist]: It is. In fact, I really don't like calling it a dysfunction, because it's the most functional way to help a child survive.

Thanks Perna for the link... I, too, often think I am going crazy, but all the T's I've had have said to me "You are far more normal than you have any right to be."
