I can't know what effects that may have on one's life. If writing a journal is a healing process that allows one to function in the world, that's an alternative to drugs and alcohol and a good defence against depression and mental illness, that is a remarkable, and creative, and valuable response to the problem. I have witnessed the functioning of a group who cared for each other, who trusted each other and who gave of themselves in order to keep each other well. There must be countless people who wish they could find such a group. I've tried to encourage people to write a journal.
People often are forced into writing by some personal crisis, later the writing becomes a journal.
If the writing continues it may be driven be the creative process, or by an interest in books, or by a search for ultimate meaning. When you get better you are interested in things in the world. The few men in the Scribe Tribe group are interesting. Ross who is struggling with a marriage break up, his homosexuality and trying to establish a life for himself. Dennis who is a professional counsellor.
