What to do when elderly Mom who lives with me won't let me out of her sight?

Mother has lived with me for the last 7 months, after my father died 7 months ago, she could not be alone, she is 86, and fell cracked her pelvis, so I moved her in with me. It has been a challenge to say the least. If I go upstairs she calls me, if I am in the restroom she calls my name, I don't leave home very often and she wants to go with me everywhere. I bought LifeAlert so I could leave the home for short period of time.. get hair done, grocery shopping ect. If I go somewhere its only for a hour or two and not very often, maybe once month. She gets so whinny, mad that I leave or not with her. I get her ready for bed and she won't sleep in a bed, only her lift chair. this is around 8:30pm. I go upstairs and read. She get so mad when I am not right with her.. she said "*I am moving out, and that I am so mean, no one can live with You" *(the guilt trip) I get her dressed, make her breakfast, get her meds, all Dr Appt, give her baths, pay her bills, ... etc... I sit with her for a hour or so.. then I go get ready for the day... I go upstairs and ck email etc... Then she starts again.. "Can you come down here and help me move my stuff? I am moving out... " I don't know if I can take this anymore.. I quit my job, gave up my online classes and don't go anywhere... I am 52 not married and adult children moved out of state, so I don't know what I can do? There is so much craziness in my home... Does anyone deal with this? and if so, how much of my life do I give up????
