Good morning, my friend. I have been to the doctor not long ago. He told me that I was sick with something. I don't know what to do, I just feel bad. I am writing this email to you to find out also how you are feeling. Please answer this question when you have time. I am afraid for my health, but yours is important to me too. I hope that everything will be fine. It is possible that it is Covid. But there is nothing to predict.
Your sincere friend,
Kamil.
