My therapist literally told me I am at the development level of a 15-year-old. Obviously, this creates problems in my life, because I have done plenty of adult things. However, in may ways my emotions are stuck at age 15. I began to experience trauma at age 15.
Studies have shown that it isn't the traumatic experiences that seem to harm us the most so much as our ability to make sense out of the traumatic experiences. (Source: )
