Advice Needed

Update: My dad passed on June 1, he had a heart attack May 25 and I made the choice to follow his wishes and withdraw life support. Thanks everyone for their support, I’d give anything to have him back. This happened just days before his appointment. I found him on the floor that morning at 5 am, thank you for your advice. I thought I’d update everyone. This happened just days after I made the post.

My dad is 67 and has COPD, he uses Spiriva Respimat. I take care of him, I need advice. I am so worried about him, he has to take breaks when eating. This has been for years. He also doesn’t have teeth but doesn’t want to go to a dentist I have tried. His issues with food worry me. He struggles with that. He’s never been one for conversation. Sometimes he sits funny, all of it just worries me. He was diagnosed in 2020, but he’s definitely had it much longer. I don’t want to lose him, any and all advice and encouragement is appreciated. I struggle because he’s my whole world and I want to take better care of him, I’m 24. My friends say he isn’t my responsibility but he raised me and I will always be there for him. He’s my world. Recently I’ve been more worried, I think it’s just the extra caffeine I’ve had but it’s gotten to me. Every 30 minutes I ask him how he’s feeling, even if I’m out I will call him to make sure he still picks up the phone. Any advice and encouragement is appreciated, I find myself worrying about every little thing he does and I just want to know if it’s normal in COPD or if alarm bells should be ringing in my head. How can I make it easier for him? How can I make things so he can have a better quality of life? How can I stop worrying? Thank you.

TLDR - Dad has COPD and I’m an emotional wreck over everything, what do I do?
