I'm so sorry you have to endure this. I can relate. I used to live in California, and it would sometimes get that hot this time of year. It was not easy. Heat can be like a prison.
What do you do to fight it? I used to take a cold shower or bath, then sit on the couch in front of a fan. It helped a little.
Sorry I can't be more helpful. I just wanted to say that I understand this struggle. You are in my thoughts. ~BK
