Katie, this is so terrible for you all.
I believe that I would rather see my son in jail than out trying to terrorize me for money for his desperate drug problem. If you have to call police, please I hope you won't feel too badly about it . I think I would be glad for the reason to put him there. At least he would be detoxing , I suppose, and safe from his choices for a while.
I am so sorry.
