trauma work is a really big deal and only you will know if/when youre ready to embark on that extremely difficult path. from what you said, it sounds to me that what you would benefit from is not regressive, trauma-focused therapy...but more in the way of coping, relaxation and improving your ability to bring yourself to a place of equilibrium....

i do hope that you find some in-between place because what youve described are two extremes that just cant be comfortable for you. *hugs*
