Has anyone lost their interest in socializing?

Or just a general lack in maintaining friendships? Sounds weird for a 4 that usually yearns for human connection, but this has become reality for me.

Weird, because I used to suffer greatly from loneliness - to the point I escaped into books and movies. I find people in general super interesting, but reality is kind of disappointing. I could vent about my experiences as why I have come to this conclusion but I know, deep down, I should be more involved with other people. It's just so hard to find people that you can relate to and identify yourself with.
