Very possibly because your level of stress is lower around those people.....I'm not sure if it just changes the way I think about it, or I don't feel alone with it, or because I've never had it, or what/ why this is so Idk?
That stress level affects EVERYTHING to do with PTSD. As it goes up the negative and the fear and all the bad stuff gets worse. It's why the PTSD Cup is so massively important in living with PTSD.
Learning how to manage and mitigate is the difference in life with PTSD. The better you get at it - the better you can function....then having the cup overflow becomes a choice than an two or three times a week accident.
