How long did covid last for you?

Hi All,
I have covid – Day 5, and I“m freaking out.
My anxiety is making it 10 x worse, just went to the Dr and she said I was doing great, but my anxiety is through the roof. I couldn’t sleep last night, full on body tremors, weird dropping feeling which I all thought were some neurological covid symptom but my Dr said it’s all anxiety – if I didn’t have the anxiety I’m sure I’d be sailing through but the anxiety is so over bearing. I’ve also lost my smell and taste which is causing anxiety even more! Googling covid is horrible as it says ’ you can feel better than BOOM you’re worse!’ so I’m like – where is the END!!! Love to hear some insightful advice from those that worry less… thank you x
