I especially enjoyed this post because I suffer from serious emotional problems including anxiety disorder. I was emotionally abused by my mother. She has bipolar disorder.
I like how you did mention toxins; I was exposed to highly toxic chemicals for extended periods of time. So the theory is that the toxic emotional chemicals reduced my bodies ability to detox efficiently and over exposure cause the anxiety symptoms among other serious mental and physical problems.
I think you just made a difference in this world.
Also I would like to mention that there is no reason to yell in the family unit; that is called emotional abuse. If you have been abused break the cycle and get help, stop abusing others especially defenseless kids! Especially if you are a parent or teacher.
