Trauma could be a lot of things. I was NEVER physically or sexually abused by anyone growing up. My parent did neglect me often (but partially because I was such a shy child that I choose to seclude myself by playing under/behind furniture, or in closets). When I was 7-8 yrs old, I had about 8 people die in my life (kindergarten teacher, family members, friends of the family). I know I felt the loss, but I didn't cry or anything. My parent also had difficulty loving me and my sisters at the same time. One of us was one parent's favorite, another the others, and the third of left out (that was usually me).

Maybe by exploring some of your past, you will find something that was traumatic for you, but not in the ways of "abuse".
