I feel angry and lost

Hi all. My husband is 44 and has stage 4 colon cancer. He is about to start another chemo soon. I feel angry. Angry at him that he didnt listen to me back in 2024 to go to gp saying I was over dramatic. I feel angry that we are being robbed of our best years and growing old together. I feel angry for postponing our plans and dreams for various reasons. I feel scared for my future. I feel scared I will not cope without him when time comes. I hate life the way it is and it has become.we have 2 children, one adult one teen. I just wanted to say how I feel. Thank you.
