Unfortunately, it's hard to convince a mother like that to cut the cords, kwim? I hope it works out for her.
If you CAN convince her that she is just an enabler and has to let her son grow up, then first things first she has to cancel the Cell phones and she should sell the furniture and truck (then cancel the insurance.) it's in her name so she can do that.
I doubt she'll do it though. sorry about the situation. That must be tough to watch
