I developed PTSD after a coronavirus. It's a very scary thing and should definitely not be started. So I immediately started looking into what it is and what I should do about it. I found very good material here
https://drmental.org/blog/ptsd on the subject and at least figured out what direction I needed to go to get over it. It was the only way I could get out of this creepy condition. I hope it's helpful for you as well.
Coronavirus came as a shock to the whole world and the impact was greatly felt, lots of people lost their loved ones as a result of the pandemic, it was a very hard blow for many people which caused trauma to many, it is good you are seeking medical advice and help on your issue, that is the major step towards getting better, you should be persistent with the treatment so you can overcome the trauma.
It is very unfortunate the world had to experience such a difficult moment, I was very scared because of the uncertainty of what will happen if things will ever be the same again, scared of getting it, but thankfully I or none of my family members contracted it.
This is the period where the whole world stopped for more than a year. We gained sufferings, traumas, learnings in life and realizations that alter our way of life. It will be years before we can say we are going back to normal or should I say, our new normal will be different. But time and time again, humanity is fighting for any problem that we are embarking with.
