Anyone else experienced this?
Yes, most if not all of us did. Constant chaos is invigorating in a sense, and also exhausting. Similar to when someone goes through an emergency situation, car crash or whatever, and they report that it seemed like everything was in slow motion as well as they felt fully alive in that moment. Unsustainable and it's up to us to decide if it was fulfilling, here on Leaving most would report it was not, but invigorating nonetheless. There's another benefit too: we can't focus on our own stuff if we're spending all of our time reacting to someone else's chaos. That's the birthplace of codependency.
The good news is once we can be alone with our thoughts and start focusing on us the fog clears and we can start really processing what we've been through. Not pretty at times, but always fruitful. Take care of you!
