I hope you're starting to feel much better! And I empathize so much--even after the booster, in that short, glorious pre-omicron week, I wasn't ready to. let my guard down. I worry especially for my parents, who are fully boosted and overly cautious, but who would not fare well if they catch it. It's a miracle that they haven't yet, really.
You've done nothing wrong! Most of those I know who've caught the "mild" omicron have been sicker than ever before, and all are fully vaxxed & very careful. Hang in there and you rock!
