Sounds like same-time-of-year, anniversary dream but too, maybe you blame yourself for something? Don't feel you're doing enough? I think if people make outrageous accusations, we know they're outrageous and it just "annoys" us. But when it makes us anxious, it's because there's a bit of poison still in the wound?

I remember when a boss humiliated me and made me cry at work once and I got to thinking about it and it was because some of what he said was "true" only I was doing my best, working on the problem, but couldn't quite fix it yet. People sometimes deliberately use or stuble upon old issues that haven't quite been resolved and that hurts. Do you see/still see a therapist? I'd look for poison near "it was my fault I was abused" and see if you find anything. Getting that out might make you more comfortable and able to see present outrageous accusations as what they are, outrageous.
