When I cam across the below referenced entry on loneliness, it gave me pause. I know that even though I appear to be outgoing at work and in social situations, that is actually a learned response. I am really an introvert by nature. I find it so easy to spend my non-work hours without being around others, content in myself, my interests, and my home. Any errands are dispatched quickly, so I can return to our little sanctuary. As I target retirement in the next decade, people often comment on how I will never stop working. They have no clue :o)
Below are some interesting thoughts regarding loneliness:
loneliness and solitude are different. Loneliness feels draining, distracting, and upsetting; desired solitude feels peaceful, creative, restorative.
Nurturing others -- raising children, teaching, caring for animals -- helps to alleviate loneliness.
many people need both a social circle and an intimate attachment.
try to figure out what's missing from your life, if anything. The more clearly you see what's lacking, the more clearly you'll see possible solutions.
take steps to connect with other people if necessary.
