My dad passed away 3 years ago and I am an only child. My mom and I have never really been close. She is 78 and has never said I love you. She now wants me to do everything for her. I work full time but she wants me to stop and talk everday. She has always been healthy until recently when she complains about everything. She doesn't want to leave the house. I am not sure why. She has no friends. Just me.
