Walking the thin line

I have tested my body to the limit this week, emotional stress, physical stress, and time pressured.  In general I've coped well, but since Friday I have really felt that I was in danger of an enormous crash and have been worried by that.  I didn't go to the hydrotherapy pool on Saturday this week knowing that I had an extremely busy day ahead, infant I had to go to bed on Saturday afternoon.  I stumbled on, the thought of a forthcoming holiday keeping me going.  Sunday was equally as busy, but I foolishly thought that squeezing in a Sunday afternoon yoga class might help make me feel a bit better...WRONG!  My baseline heart rate was already raised and anything requiring me standing or using muscle strength made it shoot up.  I couldn't do much and didn't feel good.
After yoga (4pm) I wanted to go straight to bed, but other commitments meant it was 7.45pm before I got there.  These past few years have made me very good at listening to the subtleties of my own body and knowing when it's not happy, and although I have without doubt improved in this area I still struggle to just STOP when I really should.
The next few days are still busy but better than last week and then on Tuesday evening I can relax completely.  I then intend to do nothing for 4 whole days, a very well deserved (if I say so myself) and needed break.
