WTF???

So I got home and right away the phone rings and there is a complaint about M and the gf and they've been at the condo in the clubhouse hanging around. They don't want them there and the police will be called if they stay there or go there again. Nice. Then when B is done with his drug class, he is slurring his speech. I know he's been using something. Then he is sleeping at dinner time, when I wake him up, he is very stoned, on something. I accuse him, he denies it. I accuse him, he denies it. Finally, he admits to using xanax, again. This is the reason he is expelled from school. I guess he didn't learn from that trouble, from the trouble last week on Monday, from having to go to indy school, from having to go to drug classes. He is a big fat liar. He said he wouldn't do it anymore. I don't even know if that is what he was on. It could be something else or a combo of things. I am so scared for these kids and very angry. I need some support. I need to be able to be calm again. This sucks. Today I have to cancel our trip to the beach because these kids are so rotten and don't deserve to go.
