My mother was sad last night,Now I know that she has a heart diseases and kidney stone that can cause her death.I really don't know what to do coz I'm still studying.I can't live without her..I love my mother more than my self!
I think you need to ask her what she would like you to do, and my guess would be to continue living your life, but love her and help her out as much as you can while you are doing it.
The most important thing is, to honor her wishes. If she is a righteous woman he thoughts will be to you.
