I have struggled with this as well. Especially Facebook. I still do. But I just deactivated my Facebook account. It is hard. It's like an addiction. But I wonder / think / hope, that by not having it, I will be more social in real life. I'm also reading the book Feeling Loved by Jeanne Segal, and it inspired me. She talks a lot about in person relationships and dedicates a whole chapter to the detriments of online communication.
