I'm sorry. I want you to know that at least your not alone. We live in a camper since we lost our house in a tornado and right before the true cold set in our furnance blower kicked the bucket. We're in the same boat, broke and using an electric heater. We stayed around 52 or so during the night. Think positive, it won't be cold forever and it's almost tax refund time, maybe you can get it fixed or get something better!
