You can still make me laugh, desperate, no matter how bad you're feeling. Have you checked whether your stuff is still frozen?
If it's your own freezer, you're going to have to call a freezer repair man in. I suppose it is, because you know how old it is. I wonder whether moving to a new house has shaken up its internal organs.
I've known (ie. lived with) fridges and freezers that make all kinds of noises. I believe if they're old and struggling, they're using more power.
Then again, with revved-up anxiety, you could be imagining it's making more noise than it always did.
Obviously I'm talking through my hat. I know what a pain it is to have to call a repair man then take time off work to be there when he calls.
