Encouragement needed

My gmom and I aren’t close anymore because her and my hubby had some words a few weeks before thanksgiving.

My dad is out abusing substances he’s been doing this for the past 5 years now he was clean for about 14 years .

Yesterday I found out my dads mother my Mamawl is in an assisted living in hospice and she’s dieing they only give her 3 weeks maybe to live . She’s in so much pain has been for a long time I hate it . I’m trying to stay strong but I need some encouragement please .
