I myself at one point was so lonely, I did things I am not proud of.

I found that boredom lead to or increased loneliness and, for me, inappropriate ways to relieve it.

I find being spontaneous difficult. So, I schedule activities, even those that are mundane like reading, writing, and art. That takes up my time and lessens the boredom which in turn helps the loneliness.

I ensure I get out several times a week - even to people watch at the mall.

As for socialization. I was new to the area making the loneliness even harsher. Joining a Support Group and attending a drop-in program were significant factors in turning this around. There is something to be said about the social aspects of being among people one shares things in common with. I have since developed acquaintanceships and occasionally socialize outside the group meetings.

Do you have family around? My brother has actually been a great source for the development of acquaintanceships as he has included me in group activities.

Making an effort to stay away from making internet 'friends' has actually helped me form relationships in real life.

Good luck!
