Those who are addicted to substances or activities which are detrimental to their well being require assistance whether or not they want to admit it or not. Most people who are addicted to dangerous substances or activities mainly connect themselves with others who have those similar problems, that makes it difficult to attempt to guide these people in a helpful way.
What you can do is to confide in someone, who is not an addict, concerning the pending decisions you must make. You can tell your mother and father, a close buddy or even a minister and make them hear your story. Somehow, with other people’s support, they will assist you to the correct course. You also must discover a reason to quit, as most addicts just coast through life with no regard for anything at all.
