Sleepie, I hope you didn't think that I was trivialising your post, I wasn't. I do know that the struggle is real and that's why I replied. Anxiety, health or otherwise can be frightening.
I was simply trying to impart that the *challenging* of health fears can be useful, this, with a little humour thrown in to cheer you.
All of the above posts sound useful as well and I am not a doctor, but sincerely hope you start to feel better soon.
