Time to slow down

OK, I've been doing too much and I have to cut down.
It was really hard to get up this morning (Sunday) to be at my friend's for 9.30 am to do some video of us performing poetry - they all said 'Are you all right?'
So now I know that 6 different jobs in a week is too much, especially when added to a day for my Diploma course, teaching my own course Tues eve, a gym session, a 2-hour choir rehearsal and a poets meeting. Oh, and the usual mothering stuff of course. Plus going to visit a dear friend for 24 hours because she's in pain and can't get out much.
The first 2 jobs were fine, Adult Learning classes, I like the tutor (she plays music in the sessions) and it was the same format for both. The 2nd was in a new town and venue, just a little bit too far for me to travel though. Thursday was a very long day, 4 hours at the private school with an early start, then another 2 1/2 that evening for an untutored group of artists. They booked me months ago, and it was cash in hand, but again a longish drive and I wasn't back home until 10.15 pm.
Friday morning was supposed to be my slow morning, but the private school secretary had phoned in a panic on Thursday afternoon saying their other model had let them down, and could I possibly do periods 1 & 2 for them? Reluctantly, I dragged myself over there to start work before 9am, heading straight off afterwards to do 5 hours for the degree students at the college. At least they were kind to me! It was my last session for them, and I asked the tutor what was happening about my monthly salary, because I still have no idea when I'm getting paid, or how much, and I'm really out of pocket now with all the money I keep spending on petrol...
'It's all in hand,' he assured me.
So pretty grumpy today. I need time off and I need some money. Unfortunately the two rarely go together.
