Better today. Thank God. I have actually been Out Of The House! OK, it was to the front garden (that which is less than 6 feet in depth) to water my poor neglected plants, but nonetheless this is An Achievement. When I came out of hospital I was so weak I couldn't even manage the stairs; today I've been up & down them about 10 times already.
Might actually be up to going for a walk tonight. Hooray.
