Ach, I know CV and I have said this before, but rats make lovely pets. I have had four, but it became way too challenging when I got StroppDog Mk 1, who was a large and extremely efficient exterminator and was desperate to get rid of all other pets, so when my rats got old and died, I didn't get any more. Couldn't have kept Gordon, or the chickens with StroppDog Mk1, whereas current StroppDog licks his chops and drools at Gordon, but doesn't try to take his cage apart. Not that Gordon is my choice. I have just inherited him. He is big and strong because he eats his porridge. 
I am having a night off tonight and pretending it is not a school night. I had no w/e, so I feel I can allow myself an hour off now with a glass of wine.
BTM, I'm afraid your dd's sitch sounds awfully familiar. My dd had a very similar situation that rumbled on all the way through 6th form and indeed when it started was in fact what completely threw her off-course in the first term of L6th. However, even she now admits that she wishes she hadn't got in such a state about it and had just realised the friendship was over. In her case, it was 2 girls she had known since Reception. And it got very nasty indeed. And the fallout continues even now, but she said to me yesterday (coincidentally) that she wishes she had just accepted the friendship was over and walked away from it all, instead of prolonging the drama. I'm not sure what to suggest, beyond gritting your teeth and battening down the hatches, but in essence they are all very stressed at this point in Y13 and every tiny problem is magnified x 100. And it's really hard for them to get away from each other if they need to. Actually seems like a very unhealthy situation, now I look back on it, but I'm not sure what anyone can do to stop things like this happening.
MrsS, I can only offer sympathy. I have several years' of experience of dealing with a distressed dd who refused to engage with any offers of help. And it continues. You can only make them aware of all the possible sources of help out there and make sure the school are doing their best to get her to talk to someone. Is she talking to friends? It's only very recently that dd has become able to open up to her friends when things are tricky. Some people just don't find it easy. Surely there is some form of "official help" on offer linked to the legal stuff? I have found it useful to keep communication lines open using FB messenger to send links about various things and then I can see that they've been open and I quite often get a positive response, which I wouldn't do if I gave her the same info in person.
I would now like to pass on some info about varifocals and computer use: as a full-time glasses wearer, I have been wearing varifocals since the tender age (!) of 42. For my everyday glasses, I have quite a generous reading section in the lenses, but in my sunglasses I make do with cheaper lenses and a tiny reading section. BUT I could not do without my computer glasses - and any optician worth their salt should offer you computer glasses if you tell them you spend all your working hours staring at a screen. Both Dh and I have computer specs which can only be used for computer work. The focus point is set at xxcm, so they are perfect for using at your desk, but will make you feel seasick if you look at the other side of the room. I chose a free frame and the cheapest (obvs single vision) lenses and they therefore cost v little. And I care not one jot what I look like when I am working in my home office. Obvs, I don't do it much any more, but they are still invaluable for when I have to spend 4 days writing an assignment! If I worked for 8-10 hours in front of the computer with my varifocals, I would have a very stiff neck and a headache by the end of it and it's simply not a good call if you have to put in those kinds of hours every day. Here endeth the lesson.
