How do I save my mom's faith?

It’s Christmas time again and of course were all stressed out. My mom usually gets the most stressed out of all of us but this year has reached an all time high. She’s stuck in a horrible job, hasn’t been in a relationship since her and my dad split (17 years ago), and has spoken multiple times lately about questioning her faith in God and how “Christmas loses its meaning as you get older.” I’m just very worried for her. My sister and I are in college so it’s not like we’re around a lot to comfort her. She goes to work and then comes home to any empty house (besides the 4 cats). I just don’t know what to do to save her spirit. Any thoughts?
