Bangalore heat with power cut is making me mad

I live in the top floor(terrace just above) of a apartment and the heat here is making me crazy. My bed is hot, my fan isn't giving enough air, it's hot air everywhere. I in general sweat a lot. When I go to sleep and wake up, my entire bed is wet from sweat and can't sleep for few hours because of the heat. For the entire day, I am shirtless and still can't take the heat. To make matters worse, electricity goes at anytime even in the middle of the day. That time, it feels like sweat won't stop at all. I don't have an AC here or power backup and the heat is fucking with my mental peace. Even the water from the filter is hot water🥲
