Fiz - based on your description, you're not paranoid, except in a colloquial sense, you're just aware of your poor health and trying to look after yourself and the anxiety of it is scary.
For ages during the pandemic, I thought I was over-reacting. Then I told others how I've got anxious about all sorts of stuff, which for me builds on my ritualistic but dottily arbitrary pre-pandemic clean/dirty obsessions, and realised how many others are also anxious for lots of reasons, just in different ways.
I'm not underestimating or belittling your stress levels, I'm saying that from where I'm sitting, reading what you write, they seem to be understandable.
The only way I've try to work out what does or doesn't seem reasonable precaution-wise and for me (which isn't how everyone would do it) to try to map it onto my own peculiarities, which happen to be rather ritualistic. I can't see that any of us could be 100% safe unless we climb a mountain and self-isolate. Hmm, but what if a bat flew into our cave? (Yes, my crazy humour is my own defence to this scary pandemic madness.) You seem to be doing what you can.
Oh dear, now there's the thank you cards I bought to send to two people, but they're not cellophane wrapped and I isolate paper/card for three days before...oh, the advice has changed and we don't need to worry about paper? How on earth do we keep up?
As I say, please don't take my use of humour as underestimating what you're going through. Big, big hugs. And they're virtual so I haven't sanitised them and you don't need to.
