I have never thought that loneliness can be very danger until the V. Tech shooting. That guy was lonely. All above suggestions are great and try something today. I will suggest spend your time doing whatever you like than just to feel lonely. WHen I am lonely I go and take a good bubble bath with lots of candles and music it makes me feel good and after than I might spend my time going to the mall or even wal-mart and just walk around. You can do simple thing but do not be lonely. You can read some thing or take your photos and start looking your loved ones if you do not want ot go out.
