Wow....sorry to hear. Need more info such as; 1-What is your water source? 2-Is your underbelly enclosed? 3-Did you leave cabinet doors open to let heat into those spaces where any plumbing runs through?
If you have a water spigot coming out of the ground, did it freeze?
Find the cabinet or access panel inside in the area where your hose connection is connected outside. If it froze there, then removing the panel may allow it to thaw (a hair drier in this case would help speed up the process).
