Living in Hell

I am actually living in hell right now. It's about 90 degrees in my apt., and only hot water is coming out of the faucets. It's so hot, it's difficult to breathe. Can I control the heat? No. If I could, it CERTAINLY wouldn't be stuck on the "hot as fuck" setting. And since it's Sunday, there is really no way of getting in touch with my landlord. I called a left a few messages, but that won't help.
So we're actually living in hell. It's 20 degrees outside, I'm wearing shorts and a tee-shirt. Have I mentioned I'm ready to move?
