It is so hard to achieve peace of mind, some people go through therapy, counselling and even taking drugs whether medicinal or substance abuse. Peace of mind is damn expensive and affects all parts of our lives. I cannot talk about peace of mind with touching God. The battles we face in a place where we can't touch is a battle beyond human ability and it is why God exists. The mind is a very tricky ever changing place to be in and never constant. As a christian I feel lucky I can talk it out to a being that can understand even when I lack words to explain how i feel.
