Hug little Liz the way the adults in your life couldn't. Really! Imagine yourself as a kid. Imagine holding her, hugging her, her head on your shoulder. Comfort that precious little girl.
This is the uncomfortable part of growth, where you're exhausted from clearing out all the debris (been there, done this, threw out the pile of t-shirts). Take care of yourself, keep going to all the counseling and Al-Anon, and pamper yourself. Get lots of sleep -- your brain is trying to reconcile all this new information about feeling emotions. And remember that emotions are just emotions -- you don't have to *do* anything about them. Just feel them, then let them be.
