Hello there, and thanks for asking just answer. I am sorry about your son's problems withmeth. You have done the right thing to say that you will not give him money foranything and that he has to earn his own living. I would suggest that you join Narcanon andread about codependency. I suggest the book Codependent no more. The way to be supportive is to take care ofyourself first. Do not go out of yourway to do anything for your son that he can do for himself. Make it clear that your house is open for himto visit and you will have a relationship with him only when he is clean and sober. Tell him that you love him so much that youare willing to change your behavior and not enable him. I think seeking yourown therapy to deal your anxiety that your son's using drugs is causing willalso help you. You have to be willing toclose your door when he comes to visit or calls high. Tell him that you believethat he can stay sober and clean. If hevisits high tell him to come back when he is clean and sober. It is ok to worry about what will happen tohim but do not give in to what he wants to reduce your own anxiety. This will help him hit bottom and get into areal recovery. Your own recovery fromco-addiction and codependency will help you also. Getting a support system and going tomeetings for codependency and Narcanon meetings will give you the supportsystem of others who have family members addicted to drugs.
Hello there here is the codependency meetings web. The web can explain more on codependency and the groups are free
Those meetings are for family members of addicts. Please let me know how it goes.
