The correct answer to this open question is the following.
Your question is incomplete. You have to write ypur feelings about what. What situation?
Although you forgot to include this important information, doing some research it seems that the part that is missing is that you have to share your feelings about your reaction to the pandemic.
If that is the case, then the correct answer would be this.
Hi John,
This is a short letter to share with you my feelings and reaction to this pandemic.
As you have noted, a lot of things changed. Many people live in fear, and some others in confusion. There is a lack of information that is misguiding people's perspectives. There are doctors and specialists that say that you have to protect yourself with masks, and to stay home, meanwhile, other serious doctors and researchers say the opposite.
And the worst thing is that mass media, tv news, and the press, are only sharing one side of the story. Opinions of specialists, researchers, and medical doctors who have a different view have been censured or simply, their opinions are not reported by these news companies.
My family and I have found very interesting perspectives from these different opinions that just want t inform, and not create fear. That is why, we are taking basic precautions, but we do not live in fear, we do not use a mask because breathing our own carbon dioxide all the time is counterproductive for our health, as many experts say, but we respect other people´s views, as we like others respect ours.
Hope you and your family are doing right.
Please, say hello to them and I wish you a happy Thanks Giving
