I was the same. Sounds like you got it worse though. Still recovering after a week. I homework but still couldn’t physically work for 3 days. If it had got much worse was going to call hospital.I was kinda sold on the belief that this variant is just a cold. I was almost relieved to test positive so I could get it out of the way. But, it is not a cold. I’m young, fit, healthy and vaxxed yet I’ve not been as sick in my life.
10 days of it and only now am I starting to feel vaguely human again. All the symptoms are crap, but the worst for me were all the mental symptoms. Zero concentration or desire to do anything… memory, cognition issues.
Hope you recover fully soon
