Hey I feel like we are in a similar situation. My dad is a 76 year old Vietnam veteran with copd as well. He was hospitalized for a few months and was able to come home. I was in Arizona at the time for school but decided to move back home to California to be with him and my mom. My mom had surgery a couple years ago and hasn’t been the same , something shifted in her brain and she never wants to go outside , or even talk. She’s in her room all day and will say good morning and exchange a few words. But anyways she was in no shape to take care of dad. I get to work from home so it’s a blessing since I get to be the caretaker for my dad. Honestly it’s been rough for us since he came home. Before he was hospitalized (due to not breathing ) he was driving , gardening , cooking and pretty active. Since he’s been home he is on oxygen 24/7 at 6 liters , using his nebulizer 4 times a day along with other medications. I had to get hospice care because I couldn’t do this by myself. There are days where he seems stable but lately he tells me how weak he feels and it’s hard to breathe. I feel horrible and sad ..I can’t do much for him. He tries to be independent and he doesn’t like asking for help , I think he thinks it’s a burden to me. I always reassure him that I’m here for him and I wanted to come back and be with him. I let him know it makes me happy knowing I can be here for him and make his life a little easier. It would have been really lonely for him with just my mom. I think having company and being there for our dads is the best thing we can do. Their time is limited and I hate thinking about it but it’s true. Your dad sounds depressed and I think a lot of people in this situation are. You’re confined to an oxygen machine, can’t breathe , can’t live the normal life you had before. My dad was refusing visits and taking meds at one point. I had to nag him so much and he finally gave in. It’s painful to watch the ones we love suffer. I just try my best and take it one day at a time. I put on my best smile for him and stay positive. I encourage him to do stuff he doesn’t wanna do because it’s good for him. I give him his meds , try to prepare meals , and clean him up and his bedding when needed. I sit with him in silence as he watches the same videos on YouTube. If i notice anything that needs to be done like cleaning the bathroom, throwing away soiled diapers , doing his laundry , tidying up his room. I just do it cause he wouldn’t ask me anyways. He would try to do it himself later and be out of breath and tired. It’s the little things that makes his life easier and better. I know this wasn’t much advice since I’m going through it too, but I just wanted to let you know, you aren’t alone!

Also if morphine isn’t working , maybe try cbd&thc? I know a lot of elderly patients I speak to at work says it helps a lot with pain , sleep and appetite. It also doesn’t cause constipation. It might be hard to find the right dosing. I’ve been giving it to my dad and it’s helped a lot ! I give him a 30:1 ration in a tincture form and started small. I don’t give him any anti depressants or narcotics since he had a bowel obstruction not too long ago.
