Certain people distance themselves from people or things that depress them. They try to indulge in things that makes them happy. Personally, I don't like telling my friends anything in detail. I might sound weird here but if anyone asks me what I had for lunch or something that annoys me too
It's because you're not used to being asked so many questions, you're free to do whatever you want to, you can go anywhere, jab koi pochta hi na ho to ek insan ki wohi routine ban jati hai. I know who you were talking about and it's really nice that people show concern. I just don't talk much when it comes to certain things. I do consider you as a friend but I just don't want to pressurise people with stories
