We all try to understand other people and make other people understand what we feel. But no one really understands your life, struggles, decisions or reasons. All they do is to fit your situation to something they have experienced and act accordingly. They do not understand the complexity of your situation or the toll it takes onto you. They do not face the same threats as you, nor does their adrenaline rise in response. When someone says they understand, they only fool you!
No wonder most people do not understand or misunderstand how you feel.
