Well, I finally got through to the lady at SS that I spoke to originally. Had to go round the house to get to speak to her though. She was surprised my b.i.l & ex were angry and asked Why? I said that they are all 'buddies' [due to smoking pot together] and s.i.l is able to hook them in.
She said I should have asked to be anonymous from the start and as I hadn't then the info would be free to give! She couldn't give me any info as all confidential, but said that she hadn't dealt with it, it had been passed on. So, I'll never know, but even so I'm sure the only thing that would have happened would be a phone call to my estD asking how she is as her mother was concerned.
Couldn't get off to sleep again last night, as it was just going round and round in my head; why does her dad & uncle not help her, not see her on her own so she can talk freely to them about her situation. As I've been blocked by them, I can't relay this to them, but I am going to try to send a message to b.i.l tomorrow morning as they are meeting my estD & her H then.
Finishing on a nice note; My GD's 10th birthday today, she is having a party on Saturday, which I will go to, just to keep my DD company. Yesterday, same GD had a play about Shakespear, which I went to and it was really very good.
