As someone with a history of loneliness, I’ve have no shortage of businesslike interactions with strangers and acquantiances. The problem has always been a lack of close relationships with emotional weight. The effect of superficial interactions on my mood is neutral at best, and sometimes negative (as a reminder that my interactions stem from business necessity and institutional circumstances rather than interest and choice).
I recently realized that I am using (overusing) text-chat to compensate for a lack of real face to face interaction. As such I have deleted all my instant messaging accounts, in an attempt to force myself to face the loneliness and get out and meet people. (Also eliminated YouTube and surfing, for the same reason.)
So far, I'm just really sad and lonely, but that's a good thing, because I was already feeling that way, I was just suppressing it with technology.
I'm checking out communities in my area that meet up regularly. Most of my friends hang out very rarely, and I'd like to meet people and join organizations that meet up on a regular basis.
Also have been working on my social skills and limiting beliefs: learning to make small talk, remember people's names, and recognizing unkind thoughts about myself, which create anxiety and prevent me from beginning or continuing conversations -- and choosing to think kinder, more constructive thoughts instead.
The big "aha" moment for me was realizing, there was an age for me (about 9 years old) when I wasn't shy at all! Because I didn't have all these shitty beliefs about myself. So I've been exploring them, and letting them go.
