Can she just throw me out and cause me to be homeless?

My landlord asked me to move and I have agreed to do that but it has turned into a nightmare for me. Her reason for asking me to move was based on lies told to her. I was not late on my rent and have done nothing to harm her property. I’m 65 years old and disabled. I live alone and have very little help to move all my stuff. I’ve got everything in my house packed in boxes but I've not been able to find a place to move. She has not taken me to court so there is no eviction that is court ordered. Yesterday, she had the water company shut my water off and put a lock on it. How can this be legal action by her? How can I get the water back on? I've told her that I have the rent for this month but I'm not going to pay her a dime until she turns the water back on. Can she continue to deny me water? That seems inhumane to me.
