This is a way of helping yourself to sort out your problems. If it does not have any negative influence on your life, you do not have to worry. Most people have two persons wishing different things in their head. But they no not think of it as their bestfriend. You need help with your depression. Ask your parents to take you to a child psychotherapist if possible.
