That's a good question. At first, I thought unequivocally, No. I have schizoaffective d/o. For me, online communication is how I interact with the world. Without it I would be even less in touch with people b/c I am unable to be around people IRL. Even communicating online is difficult for me.

That being said, I think that there are people who lose all touch with reality when they immerse themselves in the online world. Not sure how that is affected by e-mailing.

I guess I didn't give you much of an answer.
