oh sally, how i can relate. it's been 95-98 here for a couple of wks.
our humidity is low but still. nothing puts me down faster than being too hot. i get very weak and very tired.

i do have a small, narrow cooling collar i got a walmart a few summers ago for under $5.00. boy, you be surprised at how good it works. get the blood in those ol carotids icey cold.

the fan with even a water mister is a good idea. and closing drapes to morning sun helps too.

is that wittle doggie really yours? what a sweet thing what's his name?
you could train a little dog like that to go inside. say on a paper in the kitchen. my friend has 2 miniature dacchies and when she leaves them for work they know to do that.

i've also seen cooling things you can put on your wrists. it's the pulse points that help the most. even some cool pacs in your groin can help.

this time of yr i bet you could find a lot of those things at walmart or target. call ahead to make sure.

also, have you considered one of those services where you wear a watch or pendant and you can press it if you need medical help, like when you can't get up. having a plan in place just in case may take some of fear and stress away.

sure hope you get some relief.
thinking of you.
