How to be there for Mom

Hey everyone. New to this community so apologies if I don’t follow the guidelines adequately. Long story short, my mom’s 60 and suffers from MS. Late last year we lost a close family member and it’s taking a toll on her, as well as her MS has ramped up (probably connected to her poor mental state) and it’s difficult for her to move / use her body. For a few months now, she stays in bed maybe 20 hours a day. What can I do to help her/be there for her?
