My mother's in rehab for physical therapy and not happy. She's mad and not cooperating. She tell me I'm not going to take her home, she's asked me if I'm trying to kill her and several other mean and hurtful things. The staff tells me this is normal and not to worry but it hard. She's has a urinary tract infection from the hospital which they are treating with antibiotics which is messing with her mind. I'm new to this and it hurts to see her in this condition. How can I get her to calm down and trust that i will take her home one day and to take the time to get better?
