Wow Twofish...you've had quite a day. I'm afraid to say but your girls are manipulating you by fear. Fear that if you don't do exactly as they demand they may relapse. If they relapse it will be because of choices they have made not because of anything you have done. You have received some really good advice here tonight. Can you stop being so available to them? Have you been able to establish any boundaries with them? I think one of the most concerning things is your son is watching his sister's manipulate the hell out of you. What happens when he begins to display this type of behavior? He may begin to believe it's the way you get attention. Big hug to you. Practice the word "no"...your girls are resourceful...You don't have to fix everything for them.
