Spoke too soon!

You would think I would have learnt by now. If I'm feeling positive I should keep it to myself, because it's clearly a jinx. Although naturally all the doom and gloom should be shared via this blog - otherwise what would you all do for entertainment? ; )
So yesterday was another good day - so good in fact that I remarked upon the fact to Miss T during bathtime and she agreed it had been fun.
Today has not been. There's not been much difference - we were out this morning, then we fed ducks, but then it all went wrong.
When I think about it honestly, I know it's nothing to do with her - yes, she wouldn't go to sleep when I expected her to, and she pulled the dog's hair, and washed her hands in their water, and had various strops - but that wasn't the cause.
So what was? Partly the fact that I'm stuck at home with no respite - even the work I'm doing at the moment, great though it is, is done from home.
Partly the fact that I was reminded of my atrocious lack of self-esteem - a simple request for a head shot was enough to send me into a spiral of panic and wondering if I could get away with submitting a pic taken four years ago!
Partly frustration that I didn't achieve as much as I wanted in the last two days because of her lack of sleep and trying to help.
And partly - and I know this is bad - a searing jealousy that Mark has been out at work all day and gets to go out tonight as well. It's nothing I haven't done a hundred times, back in the days when I had a job to go to (although mostly my evening excursions were for work as well) but on a day like this the hours are like an endless night and a two hour break just doesn't seem enough.
Of course it will be, and of course tomorrow things will look brighter, but today I'm wondering where I put my lovely therapist's number, and if we could scrape together the money for a rescue-and-restore session with her.
