When I was a kid, I was very talkative. My parents liked to say that I started talking a bit before 2 and hadn't stopped yet. Then, around 11 or 12, my depression "kicked on" and I pretty much stopped talking. They started complaining about that instead.
These days, I could talk for hours to my wife about everything and anything, but she's the only one. Outside of interacting with her and my daughter, I don't really say much. Socializing is difficult, even with them sometimes. There are moments I have to just leave the room because I can't deal with any more talking, either from me or to me. I used to stay and try, even though I couldn't think of anything else to say or process any further information. It never ended well. Now that I've finally figured out what's going on, I don't feel the need to "try" when I know I can't do it, and my wife is fairly understanding about it.
