When feeling the hard emotions of persistent pain, we must go through the tunnel; to heal we need to feel

If you haven't heard of the train analogy, it goes something like this: Difficult feelings are tunnels, and we are trains traveling through them. We have to move all the way through the darkness to get to the—peaceful light at the end of the tunnel. The important part is we NEED to keep moving all the way through to the other side of the tunnel and feel all the feels.
