Do you feel like mind shuts off when you’re worrying or thinking too much about something?

I don’t know why I feel so quiet today like even overthinking has stopped and mind just feels blank. It’s very weird feeling. Too much feeling of overwhlemed and defeat. Not sure why

I’m just kinda tired mentally looking for clarity and answers or finding the why to the problem or situations. It’s like why am I even trying to figure out everything when I’m not even taking actions and getting out of comfort zone nor do I forgive myself about past events such as failures and regrets. An entire year went by and I look at myself and trying to find something good I did. I can’t find anything to be proud of.
