So the "me" I want back is who I was five to fifteen years ago.
On the presumption (general consensus presented on this forum) that ptsd is not curable), I feel the goal of getting back to "you" is too large to achieve within a short program, and a perception of failure (if you failed to achieve an overly optimistic goal) would not be healthy for you.
Is there a smaller goal that you could aim for. One of the quotes I love is "small enough to acheive, big enough to matter".
