Any caregivers have experience with late stage lung disease?

Mom has Intesestial lung disease and now having mobility issues. Thinking of getting her in home palliative care soon. She has been terribly sick lately, and I'm sure her condition is progressing, but I'm not sure what resources to tap into, but I know I need help, badly! She hasn't been able to walk alone for almost a week. It's scary, and not sure how I will handle losing her but I know her end is inching near. I'm calling her lung specialist today to ask about palliative care. If you have any tips or advice I'd greatly appreciate it. She is needing more care on the medical side than I can provide currently. God bless.
