You did the right thing, intervening would have only put yourself in harm’s way. It sounds the aggressor may not only have mental health issues, but meth/drug issues as well, and you can’t know how they’re going to act at any given minute.

Try to occupy your hands and brain with a physical task - a simple game (Tetris, or a simple puzzle game) can help with processing what happened.

You’re going to be okay, sending you good vibes and love 💜
