Idk what to do about my mom

I’m 32 and married but my parents got a divorce when I was 27, a year after I got married. My moms been living in an apt alone for the last 5 years. Both her parents passed away within that time and my husband and I moved 2 hours away for his job. My mom has a great job but she’s super depressed. She used to be the most bubbly outgoing person I knew but she doesn’t enjoy anything anymore. Idk what to do for her. She doesn’t wanna go on a trip or anything. I’m going crazy idk what to do. 😭 she’s my everything and I feel like her spirit is so broke and it’s crushing me 😭
