Ruminating and Trying to Resolve Friendships Gone Sour

I sent an apologetic e-mail to someone I haven't spoken to in a couple years. Unlike at least a couple people who have dropped out of my life over the last decade or so, this person's ending communication doesn't come as much of a surprise. They revealed an insecurity to me, then I essentially told them I didn't want to hear it. Haven't heard anything from them since.

These types of things stick with me. For awhile, I made huge deals about them because my mind would unconsciously ruminate upon them while letting my conscious brain eavesdrop. It was something of an obsessive thing. After learning more about ADHD and that I have a minor case of it, I had an easier time just letting my mind chatter and telling myself that it didn't really matter.

Nonetheless, there's something about me that really likes the idea of being close friends with people and connecting with them and networking and making more friends. I'm not necessarily the best at all that stuff, but I just keep trying. I kind of hope that my recent humbling will open this door to a pretty damn interesting, if very quirky person and could possibly help improve both our lives.
