Yes. According to a study on over 17,000 middle-class Americans that researched the effects of 10 distinct categories of emotionally and physically painful experiences on children - including, divorce and parental separation, emotional neglect, the death of a parent, and so on (you can read the other 7 here)...
50% of adults tested for having experienced a traumatic event in their childhood. (HALF!)
Almost 40% tested for having two traumatic experiences.
12.5% tested for experiencing 4 or more.
Therefore, trauma is unfortunately not rare for children, it's normal.
So if you experienced pain in your past that left you wounded, know that you are not alone, your past is nothing to be ashamed of, and you are deserving and capable of healing.
