Hi LadyLazarus. Oh yes, I know that I, and I'm sure many others, can completely relate to this. I think that as hard as we may try to separate our own experiences from our judgments of others, it's sometimes impossible not to look at our own world of dark hell and feel just a little contempt for the minor hiccup in the life of someone who perceives trauma as being late for their favourite tv show.
Whyever the reason, distancing ourselves from people and feeling irrational, flamable anger, is a sad, yet common, feature of PTSD. I think managing this is all about finding the balance - the balance between identifying and carefully nurturing safe, healthy social connections to help us prevent total self-enforced isolation, yet also respecting our need to step away from the undue pressure of social interactions that can be so triggering at times. I think there is a time to push ourselves, sometimes forcefully, to connect, and a time to give ourselves a break. Wish I knew an easy way of finding and walking that fine line, but I don't... maybe there really is no answer other than self-awareness, perseverance and, hopefully, some healthy connections with a professional and/or personal support network who can help to add balance to our internal world of eratic hell.
Sorry, I wish I had more hope and positivity for you, but there's precious little of it tonight I think.
