Therapist recommended
Format: Paperback
My therapist recommended this book, and I can already see why. It’s incredibly validating and insightful. It really helped me understand so many of my feelings and behaviors in a way I hadn't before. The exercises and practical advice are so helpful and feel very grounded. It's a must-read if you're working through this kind of stuff. I’m so grateful my therapist told me about it.

Great book for direction on how to help yourself!
Format: Kindle
This book, written for (as the title suggests) adult children of emotionally immature (EI) parents, provide wonderful insights into the psychology of EI people. Regardless of the emotional level of your parents, these books are a must-read for everyone. Why? Gibson kindly and directly delivers clear insights into EI behavior, which applies to any adult in your life. Self-Care for Adult Children of Emotionally Immature Parents: Honor Your Emotions, Nurture Your Self, and Live with Confidence, deals with caring for yourself in ongoing relationships with EI people. These techniques are grouped by where and when you may encounter EI people to use the book as a reference guide. If you are close to someone who exhibits EI behaviors, you can flip to that section. If you work with EI people, there's a section for coworkers. This book focuses on how you nurture yourself and your identity once you've worked on healing from childhood trauma. Gibson does a superb job of sharing direct context about EI people. She pulls no punches about EI people's damage but gives space to encourage growth and break the multi-generational trauma.
