I don’t know what to do

My mom has a condition that causes chronic pain all the time. I was sleeping at her house and I heard her violently vomiting so I went downstairs to check on her. She’s just sobbing, vomiting & praying for Jesus. There’s nothing we can do. I think she was vomiting from a heavy mix of medication and drinking to try and numb the pain. She is in so much pain 24/7. I don’t know what to do. I can’t handle watching her in so much pain. No amount of medication stops it. Nothing does. I just needed an ear. Maybe some prayers. As much as we can get.
