I don't know why I have this response to training. Maybe I'm trying to generate an effort greater than a trivial matter like moving a barbell could normally generate. Maybe I failed or nearly failed once and that's my way of preventing it from ever happening again. My life and my situation are fairly normal. Placing myself in the mind of a person who suffered a childhood of abuse and torment, I can only imagine that this kind of fear must be a part of every activity, every day.
Children are physically and emotionally dependent on the adults who are charged with their care.
Should those individuals or some element of the environment threaten a child, especially chronically, that child will not thrive. It's likely that the child would be driven to one extreme of society or another. For some, despair is a comfortable zone where life holds no value and the best situation is an absence of pain and discomfort. Hope is less than a faded memory, no more real than the mommy who didn't show up to make it stop. If I had to respond to such an upbringing, I would want to protect myself from ever having it happen again.
