interesting question ? a bit obscure..do you mean how i function in society or how i view society. i wuld say that what first sprang to mind for me is that because of PTSD my life has been geared towards making society better. i got into midwifery through ptsd . maybe i am interpreting 'function' as purpose i.e. the life purpose rather than how well i cope (how well i function0 . If it is a question asking if PTSD effects my functioning when i am out in th ewider world then the answer for anyone with ptsd has to be yes and it is not something i leave at home when i go out!!
