Hi sad daughter
it is nice to see that you understand what is going on and do not take responsibility for your mother's feelings. you are right that you will resent your mother if you move back home. you are not responsible for your mother's depression. it is her choice for not seeking help. it is your job to become independent and move on with your life. you could perhaps use your influence over her to highly encourage her to seek help each time you talk to her, that that would bring you happiness above all. welcome to psych central. you will find we have several forums where you can post about your concerns and receive feedback from other members. you will get a lot of support here. again, welcome
