How would it affect me, as someone with a pre-existing condition?

My initial experience of Covid-19 was a skull-splitting headache of the kind that you cannot get function with or get rid of. This was followed one day later by the loss of taste and smell. I felt fatigued as you would expect but luckily I did not experience any cough, fever or breathing issues. I just continued taking my fibromyalgia medication, painkillers and plenty of sleep to get through it. After a week the headaches started to lessen in severity but just as I felt I was recovering, the illness began to manifest itself in other ways.
