Chin up. High temps and stress make us all testy. You will get through it. Here in CO it was 100+ for days on end by this time a year ago, and Bob and I were bickering regularly. We spent the entire spring and summer trying to keep trees alive.
This year the temps have been more tolerable but we've been invaded by bugs decimating our trees, and birds plucking seedlings right out of the ground, and it just gets to where we feel hopeless and completely overmatched some days. Those are the days we have less than pleasant words with one another. A good night's sleep helps, and oddly enough, a meal helps. A/C in the house will make a big difference. It's like having a safe room. Spending money on something that will cost you more money every month is irritating, but so worth it when it's so hot out.
We open windows as soon as we get up in the morning (before dawn) when it's cool out, and Bob closes them when the temp reaches 74 F so the A/C doesn't kick on until it's necessary. In the coop I open the windows first thing in the morning and turn on the box fan, so it stays cool as long as possible. When I get home from work I open both doors to increase the cross breeze and water down everything, especially tree branches if there is a breeze, and the temperature difference is very noticeable. It isn't humid here, it's arid, so water-cooled air works very well. I don't know if that would work for you or not, but worth a try.
