Depending on your location... if you had trees there should be water down below. It's tough work but you can dig around where the trees would have been and find the water table. It will be challenging if you don't have much water to be hydrated with... but it could be a great source now that the trees aren't drinking. There are guides on Youtube and other places on the internet about digging the well and how to find the right spot. Dig in the morning or night so not to waste energy. There is also ways to capture the humidity out of the air by trapping it. I will have you and your family in my prayers.
