would someone be able to tell me if this is a possible scenario for PTSD?:

ive found a certain loved one close to me in two instances where they attempted suicide, both times they were comatosed and in icu and both times i was given the 'if you have to make the decision to let go' speech from docs. both times thank God they pulled through and wee okay with no brain damage etc (both were massive od's) my curiousity leaves me to wonder if my panic disorder may be something else, as i am constantly (even when i try my best not to be) somewhat of a 'watchdog' or 'policer' to this person, and it hurts them and myself, however im not sure if its related to PTSD, obsessiveness, fear, panic, or something else.. im unsure but i believe it contributes greatly to my disorder but im not willing/able to emotionally seperate myself, as i need this person as much as they need me, just im not sure where to draw the line and how.

anybody else in a similar circumstance, or been there? i somedays feel im going to drive myself crazy however my fear of losing this person is greater than anythinge else as this person is my survival in so many ways.

thanks for listenin, sorry for the long post and my appologies if its in the wrong forum.
