I agree with Pachy. I think that we get the chemical imbalance because we are not allowing our body to function as it should. I think that a lot of people have depression because they simply don't know how deal with their feelings. Feelings are natural and if we don't allow them to be expressed because of what we learned while growing up, it throws a wrench in the system and messes up the natural flow of our bodies, thus the chemical imbalance. So I agree with Pachy learn the things that you haven't yet and get your system back in balance.
