Another thought might be 'I don't need to know what the trauma might be that is causing me this distress and physical symptoms....I just want to move on forward and leave the past in the past.'
You know what you think might be trauma from this lifetime just might be from any of your past lifetimes ,so it would be quite the quest to exactly figure it all out.
You might consider just saying positive affirmations each morning to begin the day and if any symptoms pop up during the day just immediately call for assistance.....believe and know that help is there working it out for you...and put joy, happiness and gratitude for the loveliness in your life in the front of your mind. Keeping your thoughts in the now moment and on the bright, wonderful future will change all of your energies, both within and without, such as your aura.... and the negative physical symptoms will be unable to bother you with this shield around you.
Just an idea that may help. I personally just accept what has happened in my life and move on with thankfullness that it has all made me strong, insightful and knowing I am unstoppable in my quest to become positive energy for the betterment of myself, my fellow beings on earth, earth herself, and all of the cosmos. That's my goal, and I keep my eyes and all of my energy focused on helping raise all energy ....at all times.
Sometimes going 'backwards' to get answers is too time-consuming and energy robbing....just moving forward positively can make all problems just fade into the backround....causing no one any more stress.
Remember what you give your attention to adds to the energy of it....think carefully what you want to give you energy to....a positive, loving now and future...or dwell on past so-called problems.
