My mom wants me to sacrifice my life to make her happy
My mom glorifies herself. When parents plan for children, it is the parents' job to provide for the children. They shouldn't see children as retirement plan.
My mom keeps guilt tripping me. I finally told her I can't stand her and she will need to use her money to take care of herself in the future. (I have been paying for her bills.)
What kind of parents put such pressure on their kids? She thinks she has sacrificed a lot of me. She raised me for the first twenty years. I have repaid with interest already.
Kids should never be anyone's "retirement plan". I think every parent hopes that their kids will love them enough to want to take care of them in their twilight years when they may need extra help, but it should not be the expectation.
Sometimes the best thing you can do in this situation is cut off your mom financially, and your family socially (or at least the ones that you know are on the side of your mom). You are not indebted to them for forcing you onto this mortal coil. Take that money and time back and start living your life for yourself.
