I can deeply appreciate your anxiety and concern. My best guess is that they may not have tested for the COVID-19 virus back in December in Scotland as there wasn’t enough information out about it. The most recent guidelines for Scotland about COVID-19 are here. While symptoms, testing, and response are here.
Your anxiety and obsessive-compulsive disorder (OCD) would certainly have exacerbated your worry and fact that the virus was different and more powerful than you’ve experienced before. While I am not a physician and everything I am suggesting is based on pure speculation, I would suggest finding ways to get some medical advice by calling. Explain what your symptoms were like back in December and if you are having any now. The medical professionals in your country will be able to guide you from there.
Knowing what was happening then may help with your anxiety now. By knowing how to best care for yourself in these circumstances, and why the early reports may not have had the identification I believe can be helpful to you.
Wishing you patience and peace,
