Gah!
Left an answerphone message this morning and emailed the foot guy the whole sorry story to see whether or not he thinks he can help, but he hasn't got back to me. Really hoping he's not on holiday or something.
It's looking less and less likely that I'll be getting an appointment for this Saturday now and as I can't get there on his other clinic day, that will mean waiting another week. Harrumph!
Still, I managed two school runs this afternoon. Had a warm bath first, as that's seems to be when my foot's at it's best. Then used both crutches, so all non-weight-bearing and am not suffering too badly for it this evening. Which is good, because I am back to 3/4 runs a day as of tomorrow.
Did I tell you all this immobility has led to me becoming a gaming addict?
I downloaded World of Goo to take on holiday with me, as I never do anything like that and I thought it might give my brain a rest after all the statementing stress. Well, I loved it. Completed all the levels and am now working my way back through trying to get the 'obsessive' scores. 
That got a bit samey after a few weeks, so last week, while Mum was doing the school run and I was sat here on the sofa bored out of my brains I downloaded Machinarium. Finished that today, so ds1 and I have just selected another one by the same company to download. 
They are really lovely games, beautiful graphics and based around logic and brain training problems, so probably doing some good for me ol' noggin.
I feel just a bit silly, but it really does take my mind off all the crap that's normally swimming round and round with no let up.
Another positive to it is that it's given ds1 and I something in common. I sometimes struggle to get involved with stuff on his terms, because it's all Pokemon, Star Wars, Lego and computer games. Obviously he doesn't really notice I'm only feigning interest, but it has been really nice to have something we are both interested in to talk about. He is also really proud when I ask his advice on what to do when I get stuck. He came back from cricket this evening and sat with me to help me work out a particularly tricky puzzle and it was really nice. 
Who'da thunk it - me - a gaming nut!
