Seriously? Seriously! Seriously!!!!

The furnace has been jacked up to 25 and has been running continuously for the past 3 hours so WHY is the house getting colder not warmer? Why?Why!Why? Mother Nature has got to cut me some slack cuz I simply cannot afford to even open the Hydro bill at this rate never mind pay it. My hands are so cold I can barely type and I feel a breeze on my back as I sit here. The cold is seeping in through every thin wall and crack imaginable and it's so so depressing. Someone please turn off the A/C outside. I so wasn't kidding when I was asked what we were doing for Christmas and I said....'don't know about the rest of them but I'm planning on being in Florida'.
