It is difficult not to be emotionally involved in this human realm since emotions are a critical part of this planet. You already know the best way not to experience trauma: Remain in your heart source.
Trauma begins in your life when you come into your physical body before birth. Trauma is held in your body even before your soul enters it. Because trauma affects your energy bodies, typical psychological therapy — cognitive or behavioral — does not cure those effects. Trauma must be addressed in layers that include all your bodies, energetic and physical. This is why resolving trauma takes much time.
On the emotional level, you begin to doubt who you are. You might experience anxiety or depression and forget who you are. You worry about what is going to happen in life and whether things will ever get better. What does that do? It causes problems on the emotional and the spiritual levels because you forget the marvelousness of who you are.
Your happiness and contentment come from within. It does not depend on your situation. After experiencing a trauma, everything has changed, and you have to find the new you. What you believe about yourself is going to assist your recovery. If you believe you are only useful if you can walk and now you can no longer walk, your life loses its meaning based on your beliefs. You need new beliefs.
Focus on yourself during this healing process. You are the most important individual in this whole practice. When you do this for yourself, your healing affects others, increasing the light in the world.
