Loneliness has often been the worst enemy of adventurers. If you have not done so already, read some journals by modern solo explorers. Do you remember "The Dove" about the young man who sailed around the world solo in 1965? In a fit of lonliness induced madness, he set his boat on fire. If I remember correctly, he had several bouts of internal struggles that nearly collapsed his goal.

Review:
"In 1965, 16-year-old Robin Lee Graham began a five year, 33,000 mile, solo around-the-world voyage from San Pedro, California, in his 24-foot sloop, Dove. Those of us who were in our teens at the time, followed his story avidly as it unfolded in a series of articles in National Geographic magazine. The book fills in the details of the personal struggle that went along with the pleasant, scenic adventures shown in the magazine. This book is a must-read for those of all ages who love sailing and crave adventure"
