Conquering codependency and shame helped me A LOT. There are Codependency no more podcasts too - and they are very, very good. You'll get it - keep reading, keep working, keep focusing on yourself. Healthy reactions will become more natural the more you do for yourself!

Depending on what type of reading you're looking for I'd highly recommend:

The Shack - William P Young

Who Moved My Cheese - Spencer Johnson

The Gifts of Imperfection: Let Go of Who You Think You're Supposed to be & Embrace Who You Are - Brene Brown

Perfect Daughters - Adult Daughters of Alcoholics - Robert Ackerman

Why People Don't Heal & How They Can - Carolyn Myss

The Four Agreements - Don Miguel Ruiz
