I'm just curious if others with PTSD find this to be something they do
Yep, all the time. Which super sucks because I work in a call center as a internet/VOP phone/PC tech support rep and 75% of my job is
ACTIVE listening, which involves shutting up and understanding what the customer is saying (and not saying), showing empathy on all of it (including the bazaillon life stuff they mention that has zero to do with why they are calling), and then fixing the issue and getting the customer to understand the issue (which is a battle in of itself when I am technically minded and most of the population is techniclly ignorant up to the point of not even knowing their PC is turned off or that wireless does not mean their modems don't need to be plugged into a cable jack on the wall).
I tend to interupt customers and also repeat myself 5 times in 5 different ways when the customer got it the first time I said it.
I do also tend to intrupt people in real life and talk about off subject topics. I do it on here too. Accidently hijacking a thread, not even knowing I did so. I think a lot of it is that my mind runs very fast. It is constantly moving even when someone is speaking to me. I think that has a lot to do with anxiety. Most of the time, I have no idea I just interupted them (or hijacked a thread on here). My therapist gently points it out as well.
I think some of it is having severe social anxiety as well but I tend to think most of it is a brain running a millon miles an hour 24/7 and with that, it is also hard to take in things people say.
It sucks to deal with! That's for sure! I think all you can really do and gently point out that they interputed you. Or just intrupt them with something like "I was saying XYZ" or something gentle like that. Sometimes I feel really horrible about it and beat myself up for it. Not that you can make anyone feel anything but I'd try to be gentle about it as they may not even know or realize they did it or do it in general. I didn't until someone told me. Then I became more aware to try not to. So, maybe a gentle talk to said person advising them that they do this.
