PTSD is all about intrusive feelings making us uncomfortable in our current situation. Recovery is all about learning to manage our behavior with the intrusive feelings raging in the background, behaving appropriately in our current situation, participating appropriately in our set of current relationships and activities. Of course you feel like you need to get away, and convincing ourselves we no longer care is a normal part of intrusive feelings. What you want to get away from is actually the intrusive feelings, but you can't get away from them, they are part of you, so you break off current relationships and activities instead.
Passing on the advice of one of my favorite therapists, the challenge is to behave in our current situation as we would have if we were not experiencing the intrusive feelings.
