Do you flinch?

I know this question may sound dumb but do you ever flinch? When a toilet seat is put down, or I’m near any cabinets that slam loudly. Even doors or other loudly sounds. I flinch and then just sigh right after, but not those typical sighs. Like I’ve been holding in something and then just letting it out.

I’m trying to stop it, because I know it’s a response to trauma but I genuinely don’t know what to do. I have headphones but in times like right now. I have them off because I wear them almost everyday and they give me a headache after a while. ( I’m in an everyday situation where I am fighting to survive in fight, flight or freeze. )

If anyone has suggestions or maybe they’ve experienced something like this. I wouldn’t mind reading and hearing out.
