hi friend,
i have a huge problem with this. its just an involuntary stream of embarrassing or traumatizing or painful things that have happened/could happen and it really cripples me. i make physical reactions that i cannot control and it interrupts social things and is just generally unfun because sometimes i get asked if im in pain based off of the noises or tics i can have. my brother has tourettes syndrome, but i dont believe what im describing is that, although it could be for you. although youve said this is a reletively short-term thing (few weeks). is it a specific memory/memories that replay or is it random events with no correlation? some kind of common theme? this is what you would discuss with your therapist if you have one and brought it up to them.
