Sometimes,
those who have experienced an unpleasant event which involves physical threat can develop symptoms of post traumatic stress. I have experience of working with people who are suffering continuing
problems following a life-threatening event.
I'm often
asked if a doctor's referral is necessary. No, anyone can do psychotherapy at any time they want. So it is your decision.
But some clients like to speak with their general practitioner first before coming to psychotherapy.
