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.
