I really wish I had better answers. My antibodies were >2500 also. My Rheumatologist said that was high also. I don't know if your doctor is right or mine, as mine told me not to get boosted. I tend to get everything but COVID at this point. Unfortunately anything I get is overwhelming. Have you had COVID more than once?

I am learning to be the glass half full type of person. Looking at any good thing, health wise or other as great. It is not easy on some days. I have found things I can and enjoy doing in my new normal. That has helped a lot. I am working on a family history and making memory books for my Grandson for each year. Catching up on years of not watching TV. I used to be a reader but sometimes I struggle with that. My brain fog is not fun. But I am alive and a survivor.

I hope you can find something you can do and enjoy in your current normal.
I wish you better health, good luck with living in your new normal, and that we will have a better new normal at some point.
