It can vary massively from one person to another. Some of my colleagues have antibodies but don't remember ever being ill. Myself, I felt terrible for nigh on 6 weeks but not bad enough for hospital. I lost my sense of taste and smell around 4/5 days after my symptoms started. It came back very slowly about 4 weeks after that but even now 25 weeks later I still can't taste or smell some things properly. Some things have a weird background smell that's the same as each other. Coffee, farts, sometimes beef when it's cooking have this strange smell included that was never there before and smells the same for each. They all have similar smells to previous included but they aren't as strong anymore. It's really ****ing weird.
I have colleagues who still struggle with doing anything more than walking around, start on stairs or try and increase anything form a stroll and they struggle shortly after. Another is still off work and he's been off around 21 weeks now with high blood pressure, breathlessness, heart palpitations and one or two other things on top.
I hope you aren't too bad with it, the ongoing issues is only with a few that I know who have had it so you should be ok as I know lots more who weren't badly affected as opposed to those who were. It's pretty random as well, massively overweight colleagues with heart issues had a sniffle so to speak. I know some who run marathons and are young who struggled for quite a while and ended up off work for 2 months
