The average feeling lasts 90-120 seconds. But what about the feelings we've spent a lifetime running away from? When our suppressed emotions are finally felt after years of being buried, it might knock us out. We might need to spend time befriending that emotion — neutralizing it in our system — before it can move through so quickly.
You might grieve or feel elated for a few days or weeks. And that's okay. That doesn't mean there is something wrong with you. It simply means you're human.
