I'll start sharing some good online resource, particularly focusing on the issue of Entrepreneur's Loneliness.
Blog of Peter Shallard - The shrink for entrepreneur
Focusing on the psychological health of being entrepreneurs, I find most of his articles are very good and helpful. The one on below's link is about how to tackle the loneliness we feel. Also many comments from others who are in the same club.
