My BF Got COVID-19 and I'm Trying to Help, AITA?

AITA Part II So bf and I have covid, at least we're pretty sure, and he had to go to the hospital. I called the ambulance, and they didn't want me to go with him, so I didn't. After a lonnnng night, and by that I mean I still haven't slept and it's 10:30am, he got released and got back home around 6am. We had planned for days to go to the pharmacy to get covid tests and vaccines, and we finally went and picked up the tests and some groceries. He's weak, and so am I, but I offered to carry both heavy bags. He refused, and we each took one. On the way home, I saw that he wasn't doing well, so I offered again to take his bag. He said no again. I tried telling him stuff like "You're doing great! We're almost there! You can do it!" and he didn't respond at all. When we got home, I said, "We did it!" and asked if he needed help up the stairs. He didn't respond, and came up right then. I kept saying that I love him, and that he did a great job, but what he said was, "You know, when you say that stuff, it makes me feel the opposite." I told him that I was trying to be motivational and just help him get home, and he said, "When you say stuff like that, it makes me want to curl up and die", to which i just said, " Wow. Okay." He said, "I don't know how to respond!", and I just said, "No, it's all good." I feel like I'm the worst, but I am also very pissed at him, because that hurt so much. I'm literally only doing what I can to make him feel better, and he treated it like it was worse than trash. AITA?? TLDR- I tried giving my bf motivational talk and he literally said, "When you say stuff like that, it makes me wanna curl up and die."
