It is a truly blessed person to have a friend by his side all the time when the chips are down. Most of us are not that lucky but there is a quiet person who is ever ready to listen to you. Your inner self.
There are two ways you can communicate with him, quietly within the confines of your mind or by writing in a paper.
Try keeping a journal. Write down all the things that you want to say. Scribble anything. Sketch if you feel like it. Don’t censor, don’t edit. And don’t be afraid.
