During 25 years of providing career planning support to the medical profession I have seen dozens of situations where a massive career crisis has brought someone to seek career guidance.
Career guidance should ideally be sought before a career crisis, not during it. The next best time is after it. Career crisis management is very different to career planning.
The trouble is that the state of mind within a career crisis or even with one imminent (i.e. less than six months away) is not conducive to undergoing the career guidance process.
