Technically, I'm in a slightly similar position to yours as I had an uncommonly annoying respiratory infection during the last week of February (I am not in a disease epicenter, however, so my Bayesian prior is much weaker). I don't believe having a positive (or negative) test would meaningfully change my behavior or medical decisions and I don't feel any significant psychological discomfort about it. That said, I respect that you feel differently, that's fair enough. However, on the last point, I'm afraid that thinking might potentially prove quite dangerous. As far as I can tell (from closely following the medical literature, though I am not an immunologist and don't claim any authority on the subject) we really have no idea as to how quickly immunity decays, every single cellular immunity (T cell) study I've seen is extremely limited methodologically and we have no clinical evidence whatsoever to suggest that reinfections would have a milder course. If that turns out to not be the case, people who behave incautiously based on their test results might significantly endanger themselves.
