I just want to say how very sorry I am for your sister, her husband, for you, and your family, and will be praying extra hard for peace and understanding. I lost my Uncle to ALS in 2008, and it’s an awful, devastating disease. We all took turns caring for him, but my mom and his wife were his primary caregivers for 2 years, and caregiver burnout is a very real thing. I hope her husband has someone to lean on, even if just a brief respite a few hours a day. It can be so hard, especially when they start slipping away (if they haven’t been intubated) and oxygen levels start dropping, when the confusion and anger start taking over. Sending you love and strength.
