What should I do?

I am 27 years old and recently got married. The thing is I have been living with my mom to take care of her. She has a lot of health problems and all my other siblings left because they don’t want to deal with her. I have been living in the city my whole life and wanted to move to a new city with my wife. My mother is sick so I don’t want to leave her behind though, but I also don’t want to put my life on hold.
