Please someone help me

Find the pipes coming into your home and point an electric heater at them. If you can't go out side , do it under the sinks, and leave the faucets open a little for when they start to thaw

Happened to my mother in law. The Plummer had to I think drive a thing down to it. And think used a welder. And it was right on the line of water company responsibility and homeowner. So I think it was both payed half of it.

Do you have a well house?

We've had our pipes freeze and had to get the plumber to come out and use a thaw machine that shocks the pipes.

Leave them open and try and get some heat near them

Yes. leave all the faucets open a bit

They are already unthawed, you need to thaw then!

They’ll be fine in a few months, no worries

Typically heat blankets draped over the ground.

Grave warmer. Use propane to warm ground.

Hairdryer?

If the pipes are underground then there is nothing you can do until they unthaw. Then consider having them redone and buried deeper underground.
